After update qt to 4.6.2 version, I've rebuild qt-creator with new qt. qt-creator 1.2.1 and qt-creator-1.3.1 with this qt-version are very very slow to start and closing. 2.30 minutes for start and 2.30 minutes to close; I've checked with top -d .5. now, during this bug-reporting, are passed 7.30 minutes and qt-creator was not started yet. I'ved download last ebuild with css disabled but without changes. Reproducible: Always Steps to Reproduce: 1.install qt-creator with qt-4.6.2 2.run qt-creator 3.wait Actual Results: very slow qt-creator starting Expected Results: speed-up start
For me it's worse: it takes minutes and then crashes. Thanks for the hint on downgrading: with 4.6.1 it's fine.
for me with qt-4.6.1 and qt-creator rebuild with this qt version, work greatly. start in 2-3 seconds, close immediately and don't stay in execution for more time (5-7 minutes) with cpu-time at overall 90% of cpu. I thing that is a problem on qt-4.6.2 some packages problem.
Did you try to wait some minutes? Seems like it creates indexes for a help on first start (or if the indexes aren't created yet).
I had the same problem: startup around 70 secs, htop shows: qtcreator takes 100% of one cpu; same on (instant) windows close: around 70 sec of 100% cpu before qtcreator is really gone. Leaving the qtcreator window open for another minute or so: qtcreator stays 100% cpu, but then calms down. Afterwards close and open are within seconds.
There are known issues with the generation of the help index in that it can take very long, can't be interrupted and it can crash. These issues are tracked by http://bugreports.qt.nokia.com/browse/QTCREATORBUG-315 Usually letting the generation of the index finish should indeed make it go away for subsequent restarts.
I've noted that this bug is caused in my case with qt-4.6.2 and doc flag disabled. you think that if I enable the doc flag the bug will be shadow?
I use qt-creator 1.3.1 with qt-4.6.2 with USE=doc. After first index creation all works fine for me.
I think I should point out that we, Qt Creator developers, have no idea what this doc flag is doing. If this issue is persistent when the doc flag is disabled, it would be interesting to know what the difference is.

I saw the message than I tried to start qtcreator compiled without doc use from console, that the file isn't available (I'm not sure, cause the localized text was completely broken).
Disabling the doc use-flag will not change to much: it doesn't install the qt-creator documentation. But qt-creator also reads the .qch files from other packages, like qt.qch which is almost 10-times the size of qtcreator.qch (and takes at least 10x longer). Idea: the ebuild moves the qtcreator.bin to qtcreator (see bug #275859); maybe we could use a script which checks for the files in $HOME/.config/Nokia/qtcreator/.helpcollection (i think this are the files which take so long to build). If there are no files a message "please stand by" could be displayed, then qt-creator.bin gets started -- but this is rather complicated because the message should be a window, so a patch from the developers to create a messagebox would be a lot easier ;-)
I've made a new installation of qt-4.6.2 and qt-creator build with this qt-version and qt-creator doc flag enabled. The problem is persistent for the first program start-up. the 100%cpu usage was finished after 10 minutes, and the 2 and 3 times that I've started qt-creator, the cpu usage was turned on real normal usage. I don't understand why with qt 4.6.1 I've no problem and with qt-4.6.2 is a "normal case" lost this time at first run.
Is there any chance you could try the git master version of Qt Creator instead of 1.3.1? There have been some adjustments to the initialization of the help plugin. Mainly to make it lazier though, so it may be the problem now occurs later if it is indeed a problem in Qt.
Can I see the emerge -pv qt-creator output plz?

Upstream says that a fix is available. I will probably be released in the next version of qt-creator Closing as UPSTREAM
