Can you describe what you did in kile when this crash occured?

[Matti Laakso (matti-laakso)]

Same error here. Occurs once I exit Kile if I have used PDFLaTeX (at least).

>Same error here. Occurs once I exit Kile if I have used PDFLaTeX (at least).

If the error is so easy to reproduce it is not in kile trunk, as I can not reproduce it here.

[Andreas Wenning (andreas-wenning)]

I have updated my svn snapshot of kile in my PPA:
https://launchpad.net/~andreas-wenning/+archive/experimental

Can anyone try to test it and see if the crash is fixed there?

[Marius (felijohn)]

It seems that it is fixed for me.

Thanks for confirming Marius.

[Matti Laakso (matti-laakso)]

I did some further testing. Kile crashes on exit only if I press any of the small "down" arrows in the toolbar, for example next to "QuickBuild". The behaviour is the same with both versions.

[Marius (felijohn)]

I can confirm that I also get the crash on exit if I press the "down"
arrows in the toolbar with the new version.

Same here, Kile crashes on exit if I press any of the 'down' arrows on the toolbar.

[Andreas Wenning (andreas-wenning)]

@tbraun
I just reproduced it on a fresh trunk export; so it seems to be lurking around somewhere. svn rev. 958896 to be precise.

Are you testing with qt4.5 or qt4.4.x? Could originate from a qt difference in that case.

I was experiencing the Signal 11 crash from the default Kile in Jaunty as well, and I downloaded the experimental Kile provided by Andreas Wenning here. It seemed to have improved on the frequency of crash: now it crashes *only after* I quit Kile. I've used it for a while now, and I haven't experienced crashes when I'm working on Kile, so that's a great thing. Now the crash is only a "nuisance."

But here is an interesting thing:
After I quit Kile, "pgrep kile" still yields a Process ID, until the Signal 11 crash message appears.
If I re-open Kile before the Signal 11 message appears, the Signal 11 message will appear and Kile will fail to open this one time. Then, "pgrep kile" will yield nothing, and opening Kile again will be fine.
If I do not try to re-open Kile after quitting Kile (but apparently not completely since pgrep kile still yields the same Process ID), the Signal 11 message will appear at a random time later.

[Andreas Wenning (andreas-wenning)]

I have the same experience. The crash-on-exit seems to be delayed some times. In half the cases it crashes right after i exit kile; and in the other half it crashes later (the kile process is still running in the background).

SVN commit 962946 by tbraun:

Don't use this as parent as it crashes then on ubuntu jaunty.
I verified this on kubuntu using QT 4.5.
With debian lenny and qt 4.4.3 it does not crash.

Any explanations why this fix works are very appreciated ;)

This might have something to do with bug 403361. Have you figured out what the actual problem is and why the fix works?
