Description jordi bofill 2010-07-29 22:25:53 UTC 
Since last emerge -u world, dev-util/eric-4.4.6 is crashing with Segmentation fault at startup. No luck reemerging dev-python/sip-4.10.5 x11-libs/qscintilla-2.4.4 dev-python/qscintilla-python-2.4.4 and dev-python/PyQt4-4.7.4.

Reproducible: Always

Steps to Reproduce:
1. eric4
2.
3.

Actual Results:  
KCrash: Application 'eric4.py' crashing...
sock_file=/home/jordi/.kde4/socket-fidel/kdeinit4__0

[1]+  Aturat                  eric4


I added pdb stop (import pdb; pdb.set_trace()) just before where the crash takes place: /usr/lib/python2.6/site-packages/eric4/QScintilla/Terminal.py
the output is:

I suspect the problem is with x11-libs/qt-core-4.6.3 update (/usr/include/qt4/QtCore/QProcess), but I cannot downgrade qt-core to find out.

Here is my systems info:

Comment 1 jordi bofill 2010-08-03 18:37:54 UTC 
Updates:

Monday: Upgraded to dev-util/eric-4.4.7 but the problem continued

Tuesday: # emerge --sync | emerge -u world
eric4 doesn't crash any more. 
I tried to downgrade some packages, but I can't reproduce the crash.

Conclusion: from my point of view the bug (if such) can be closed.
