[Kde-pim] Kontact3 crash related to catalogues(bug #139652)

[Raúl Sánchez Siles]

Hello All:

I've been chasing this bug for a long time it is a real bugger, it's not
repeatable, makes kontact crash and it's quite annoying it preventing
kontact stable sessions. https://bugs.kde.org/show_bug.cgi?id=139652

I've done a lot of tests to see where the problem could be and all I posted
all the results in the BTS, but still I'm eager to find a solution to this.
At first I thought it only happened to me (just in my work desktop, not on
my laptop). But there is duplicated marked there as well, which is good a
bad. Guess yourself why.

My news now is that I've run valgrind more verbose on it, but maybe it could
be some race condition since I was unable to get it anyhow on valgrind.
What I did get is a long long stall on kontact where I think the problem
could happen, but I didn't got the SIGSEGV there. Gzipped valgrind log
attached.

After that I run it from gdb and I got it to crash after opening and closing
tabs on the akregator part, going to the knode part, looking some threads
there and finally switching to the KaddressBook part. I also had dived into
kmail part before. As I say the crash occurred again and I got some
information from gdb when it happened. I attached a summary of the state of
the app there(kontact_debug attached)

I'm totally available to give you whatever info you need to find out the
guilty of this. Believe me, this is my ever most hated bug. Needless to say
that whatever idea you could provide is valuable.

Thanks.
