Description Mildred 2013-05-23 12:34:54 UTC 
Description of problem:
When loading a file, sometimes, qt-creator crashes with SIGSEGV.


Version-Release number of selected component (if applicable):
qt-creator-2.7.0-1.fc18.x86_64


How reproducible: very often but not always at the same point. Can't keep it running for very long though (except by doing nothing)


Steps to Reproduce:
1. Load qt-creator and open files, follow C++ references, ...

Actual results: Crash


Additional info:

I used gdb to see what happened, and I got the following stack trace:

Comment 1 Sandro Mani 2013-10-17 21:53:46 UTC 
Since this bug was reported against a now obsolete version of qt-creator, I'm closing this as WONTFIX. Please reopen if the issue still occurs, and preferably file an upstream bug report at [1] and post a link here. Thanks.
