detailed designer stacktrace

I've rebuilt x11-libs/qt-gui and x11-libs/qt-declarative with CFLAGS="-march=native -O1 -mtune=generic -g -ggdb -pipe" to get more details.

Same for me.
qt-creator 2.1 and 2.2 fails on both ~x86 and ~amd64, on access to designer (Tools->Options->Designer for example, causes app to crash)

I can provide any additional info, if needed.

Try building qt-gui with USE=accessibility and then rebuild qt-declarative too.

That worked, thank you!

[Comment 7 Davide Pesavento (RETIRED) 2011-05-10 12:42:02 UTC]

We apparently need to add accessibility in IUSE for qt-declarative too, like we recently did for qt-svg, and depend on 'qt-gui[accessibility=]'.

[Comment 8 Davide Pesavento (RETIRED) 2012-01-29 21:06:37 UTC]

This will be fixed in 4.8

[Comment 9 Davide Pesavento (RETIRED) 2012-01-30 15:12:52 UTC]

Should be fixed in qt-declarative-4.8.0-r1
