Product: [Applications] kdevelop Reporter: rjwgnr27
Component: generalAssignee: kdevelop-bugs-null
Status: RESOLVED DUPLICATE

Sentry Crash Report:

Description rjwgnr27 2013-07-24 23:10:09 UTC 
Application: kdevelop (4.5.1)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.10-100.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
Editing a function, and double clicked on a variable name in a declaration. Tool-tip popped-up asking if I wanted to rename the usage of the variable. Pressed "alt-1" to perform rename. Then crash.

On restart, recovered the session, and found the renames had completed, so the recovered file contained the results of the rename.

Have seen this several times specifically with this sequence.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
