Bug ID: 368751
Summary: KCachegrind crashes after a profile gets loaded
Product: kcachegrind
Version: 0.7.4kde
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: josef.weidendor...@gmx.de
Reporter: jan...@inbox.lv
Application: kcachegrind (0.7.4kde)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Opened profile data either by using the "Open" command explicitly or by opening
the profile data file using "Open Witch KCachegrind".
The loading progress bar reaches the end and the application crashes.
It crashes when I try it with some profile files, does not crash with other
profile files.
The crash can be reproduced every time.
-- Backtrace:
Application: KCachegrind (kcachegrind), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
