Summary: Crash in kdevelop on executing "umount -a"
Product: [Applications] kdevelop Reporter: Pradeep K. Shima <pkshima>
Component: generalAssignee: kdevelop-bugs-null
Status: RESOLVED DUPLICATE    
Severity: crash    
Priority: NOR    
Version First Reported In: 4.3.0   
Target Milestone: 4.3.0   
Platform: Fedora RPMs   
OS: Linux   
Latest Commit: Version Fixed/Implemented In:
Sentry Crash Report:

Description Pradeep K. Shima 2012-04-13 07:38:04 UTC 
Application: kdevelop (4.3.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.0
Operating System: Linux 3.3.1-3.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I see the crash in kdevelop even after upgrading kate to. 4.8.2
I never saw any issue with kate before or after the crash.

Doesnt look like the fix and all duped bugs were unit tested before marking this issue FIXED.

A fix is still needed. Kdevelop is completely unusable as of now.

Reporducing this crash is very very easy ... 
1. Launch kdevelop 
2. On another konsole window, run "umount -a" 
3. Enjoy the crash.

Even a workaround will help me continue using kdevelop.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
