Recent updates to NX seem to crash randomly on my system. Unfortunately, I have only been able to consistently reproduce the crash using KDE4 SVN. Here is one way to reproduce (note: this works only "most" of the time, and there are other similarly-innocuous ways to cause a crash as well): 1. Make sure you have KDE4 from KDE's SVN trunk. 2. Start an NX session in rootless mode (i.e. with NX apps as individual windows, not with a desktop). 3. Within that session, start Kopete. 4. Open a chat window in Kopete (I am using the "kONE" chat style, if it's important). 5. Segfault. I started noting random crashes (which were not reproducible) with -r4, and they have gotten worse in -r5. I have had to fallback to -r3 for NX to be at all usable for me.
Please post 'emerge --info' then we'll assign this report to maintainers; hopefully they will have some luck in being able to reproduce the problem

The only change in -r5 is a patch in nxproxy (for nxcl), so the source of your problem must be the nxagent bump from 3.2.0.8 to 3.2.0.10: nxagent-3.2.0-10 - Extended fix for TR07F02091 to include font names having zero in fields RESOLUTION_X and RESOLUTION_Y. nxagent-3.2.0-9 - Fixed TR07F02091. Scalable fonts were not correctly listed among available fonts. - Fixed TR06F02080. Use the corrupted area extents as maximum size of the image data. To check if it's indeed nxagent, you can try this on the server (where kde is): * run "nxagent -R :1000", this creates a rootless session * run the faulty command with the DISPLAY variable set to use this, i.e "DISPLAY=1000 kopete" Hopefully you'll see the nxagent crash, which will allow to get some backtrace!
Can you try with nx-3.3.0? Release notes indicate lots of fixes in this new version.
(In reply to comment #4) > Can you try with nx-3.3.0? Release notes indicate lots of fixes in this new > version. nx-3.3.0 is still exhibiting the problem. Same steps to reproduce as before. I updated to 3.3.0 last night, logged in this morning and it crashed almost immediately -- still seems to be tied to Kopete, however.
I'm currently running kde 4.1.3 on a remote session (amd64 server), I cannot reproduce it (even running kopete). So this may be caused by your theme Can you try running the agent as detailed in comment #3 ? Getting a backtrace would definitly help
Versions <=nx-3.3.0-r3 could trigger nxagent crash when opening some applications (openoffice, firefox notably), it may be worth to try either nx-3.3.0-r3 or -r4 (not stable yet, corresponding freenx had a few changes in the ebuild)
Looks like this one is fixed now, please reopen if you still have this problem. Marking resolved test-request
