New crash information added by DrKonqi

krunner (0.1) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.1

- What I was doing when the application crashed:

Alt+F2 -> type -> crash.

Also this time KGet was opened, this still applies in KDE 4.6.1.

Comment 9 Diego 2011-05-13 11:40:45 UTC

Found a way to always reproduce on my system: KRunner -> start typing "it2en: blah blah blah" and so on. Continuing writing random chars makes KRunner crash at some point. 
I'd like to provide a full Valgrind log, if I'm able to.
Is there a way I can attach valgrind to KRunner while running or should I just kill KRunner and then start it from command line? Any option you'd like me to put in valgrind command line? Thanks.

For the record, ABRT report: https://bugzilla.redhat.com/show_bug.cgi?id=704474

Comment 10 Matthias Fuchs 2011-05-13 11:52:15 UTC

Thank you for the information.
I think kquitapp krunner and then simply krunner should be enough.
Maybe krunner --nofork is needed, though I am not sure on that.

Btw. interestingly I was finally able to reproduce a crash with what you described on #9 but only with my regular account, not with the devel one.

Interestingly it doesn't crash under Valgrind... it should be a nasty threading issue.

What do you mean with the "devel account"? Running 4.7 currently in development or just with another user account?
What's your DBus version?

Comment 12 Matthias Fuchs 2011-05-13 20:00:39 UTC

Well I have 4.6.2 here and also an own account where I run master/trunk. It crashes in the first with your method but not in the later.

You see the problem is that I don't know what is wrong with that line, for me it is valid code that tends to crash sometime for some users. :/
I guess I should remove the check where it crashes altogether. Better to not always correctly identify downloadable urls than having a program crashing.
Ideally I'd digg into dbus to see what goes wrong, though I doubt that I'll have time for that atm.

The dbus version I have is 1.4.8.

Comment 13 Matthias Fuchs 2011-05-13 23:12:23 UTC

Just in case this is what I get when starting krunner in the terminal and crashing it:

process 13567: arguments to dbus_pending_call_block() were incorrect, assertion "pending != NULL" failed in file dbus-pending-call.c line 704.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace

SVN commit 1231749 by mfuchs:

Workaround: KGet runner does not use the KGet interface anymore. That way a crash in upstream is worked around.
TODO: Reenable once the bug has been fixed upstream.
