Description jan.fostier 2009-08-19 16:46:00 UTC 
Application that crashed: kdevelop
Version of the application: 3.9.94 (using KDevPlatform 0.9.94)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.29.6-217.2.3.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Steps to reproduce:

1) Launch an application that runs a macroscopic amount of time
2) Close the tab in the run section in which the application runs

Although top shows that the application has been killed, the stop button is still active.

3) Hit the stop button = crash.

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

Hmm, its not very nice to kill the app behind the back of the job...
Comment 2 jan.fostier 2009-08-19 19:30:23 UTC 
Since I have no idea what you mean by that, let me make it clear that I 
don't kill a running application by invoking a kill command in an 
external shell or anything.  I just close the 'run' tab in kdevelop in 
which the program is running.  I noticed that closing this tab, also 
kills the application that was running in it (I assume this is 
intended).  However, the kdevelop 'stop' button doesn't notice that 
there isn't anything left to stop, and when you press it, kdevelop crashes.

I assume that simply making the stop button inactive once all tabs that 
contain running applications have been closed would solve the problem.

Regards,

Jan.

> Since I have no idea what you mean by that

I'm sorry, that was just an meant to be an ironic comment regarding the fact that one part of kdevelop deletes another parts data.
