Version: 2.1 (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages It occurs with regular frequency in my newly installed Ububtu 9.04.

Can you please give some more information? What have you done to get the crash? Can you properly reproduce it? And a real version number like the one from "apt-cache policy" would be nice too.
SVN commit 958882 by tbraun: hopefully fix at least one of the bugs ... The m_stop action in the manager might not always be a valid pointer, therefore check before dereferencing it. CCBUG: 190483 CCBUG: 190326 M +1 -1 kile.cpp M +11 -3 kiletoolmanager.cpp M +3 -0 kiletoolmanager.h WebSVN link: http://websvn.kde.org/?view=rev&revision=958882
I had produced one crash in mandriva.May be related to this bug. The way I could reproduce the bug is by dragging down a tab like forward dvi and it crashed after closing kile. https://qa.mandriva.com/show_bug.cgi?id=49645
One thing I've noticed is that, almost every time after I quit the problem, although the timing may be random, the same "Signal 11" message will show up indicating that Kile has crashed. The crash message may occur almost immediately after quitting the problem, or sometimes up to 10 minutes after quitting the problem. I've downloaded the experimental version here: https://launchpad.net/~andreas-wenning/+archive/experimental I haven't tested it *extensively* yet. It *seems* to crash less, but it still crashes quite regularly.
So I tried the "ForwardDVI tab" and then quit Kile. Sometimes, it crashes immediately after I quit Kile. Other times, it does not crash immediately after quitting Kile, rather, it crashes the next time I try to open Kile.
Actually, the "crash the next time I try to open Kile" issue exists regardless whether I tried to drag down the ForwardDVI or not. The "Signal 11" crash occurs quite randomly, and I'm kinda befuddled. By the way, I'm using the 64-bit Ubuntu.
I have to check the latest version of kile available in mandriva.The crash while opening I haven't noticed.May be this happens in ubuntu.I will check in ubuntu64 too. thanks
Some interesting info here: I've been working on the experimental version of Kile a few times now. It does not crash when it's open. All the crashes occur after I quit Kile, although the timing is random. Here is the thing: after I quit file, "pgrep kile" STILL yields a process ID, UNTIL the Signal 11 crash. Somehow the quitting of Kile isn't quitting completely. I've tried to open and quit Kile a few times now, and each time Kile "pgrep kile" will yield a process ID after the attempted quit... until the Signal 11 Crash message.

@tornio: You are also on ubuntu? And can you give your Qt version.
I had the same bug after closing Kile 2.1 in Ubuntu 9.04 using alt+F4 I can not reproduce it right now but it has happened a few times Here are the details : This backtrace appears to be of no use. This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

David LeBauer, I've gotten that same message as well, not always reproducible though.
I have the Kubuntu 9.04 and I have seen that at the next restart of KDE Kile is opened if it had crashed in the session before.
There seem to be different crashes mentioned in this bug report. I can reproduce "one" crash whenever I have changed one of the tools in the tool bar, i.e. I changed ForwardDVI to ViewDVI, and then quit Kile. Is this also what some of you guys are experiencing?

(In reply to comment #12) Do you have all the debugging packages installed(including kile-debug)?
(In reply to comment #16) > please check although I use mandriva but it looks upstream.You donty need to > change the ForwardDVI to ViewDVI, just drag down any of the toolbars and it > crashes Ok, I can confirm that. Clicking the "down arrow" (so that the popup menu expands) on one of the tool select actions is sufficient to trigger the crash when Kile is subsequently closed.
SVN commit 962890 by tbraun: disable tool drop down lists if no document is open. This should fix mandriva #49645. CCBUG: 190483 M +3 -1 kile.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=962890
So the easy one should be fixed now. This is the one from #19 which Michel described. The other desribed here should be the same as https://bugs.launchpad.net/bugs/357016. I'm trying to reproduce it here on debian and kubuntu.
(In reply to comment #20) > SVN commit 962890 by tbraun: > > disable tool drop down lists if no document is open. > This should fix mandriva #49645. I have tried with opening a tex document .Still the crash happens after clicking drop down menu.adding a new backtrace.
