Description Stefan T. 2009-08-12 22:33:44 UTC
Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    Ubuntu Packages

1. Right click on email message.
2. Create filter > Filter on Subject...
3. Select folder > New Subfolder (maildir) > OK.
4. Select all messages (CTRL+A). > Right click > Apply all filters
5. Click on new subfolder
6. Mouse icon shows that KMail is working.

After 10 seconds KMail crashes, without showing me Bug report window (application).
Comment 1 Stefan T. 2009-08-12 22:36:15 UTC
Kubuntu 9.04, KDE 4.3, Qt 4.5.2
Comment 2 Dario Andres 2009-08-12 23:03:24 UTC
You can try to get the backtrace this way:

- Close KMail
- Install the "kdepim-dbg" package
- Start Konsole and run "gdb kmail"
- Type "run" + Enter
- Repeat the steps to crash the application
KMail should crash
- Go back to the Konsole window, type "bt full" and press Return a couple of times. 

Finally paste that output here.
Thanks

This is all. Did I do something wrong?

Oops, I missed one thing: instead of typing "run", type "run --nofork". It should work. Sorry
Comment 5 Stefan T. 2009-08-13 01:26:04 UTC
I did what you told me.

It did not crash, not yet (last 2-3 minutes). I am at> "6. Mouse icon shows that KMail is working."

And here is log, after Return x3.

Comment 6 Dario Andres 2009-08-13 01:28:07 UTC
Mh, you said it didn't crashed, but GDB show the process crashed (or it was stopped manually using Control+C): 

"
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb3c43700 (LWP 2121)]         
"

Anyways, the backtrace doesn't seem to be a KMail crash. Let see further output
Comment 7 Stefan T. 2009-08-13 01:36:28 UTC
KMail stopped working. I can see Kmail, but Kmail doesn't respond. More output?

This is what I have. After x 10 return. That is not all, I closed it after that.

Comment 8 Dario Andres 2009-08-13 01:44:17 UTC
The backtrace looks like the output from bug 186265 comment 4 (and situation seems to match too). 

Thanks for the output, I'm going to merge the other report here. Regards
Comment 9 Dario Andres 2009-08-13 01:50:31 UTC
Bug 186265 also showed another testcase scenario.

Check for bug 186265 comment 4 and bug 186265 comment 5 for more references of the long backtrace (50000~ lines) showing a repeated pattern (overflow..):
