Comment 1 Dennis Nienhüser 2011-01-20 23:42:34 UTC 
There are 48 (!) threads running and the application is terminated running out of memory. While that happens when Marble loads a file, I doubt the crash itself is related to Marble. I rather suspect that something else is wrong, the sheer number of running threads should be a good place to start to investigate.
Comment 2 Adam Spiers 2011-01-21 00:19:08 UTC 
I think I can reproduce this fairly reliably, and am happy to help debug.  I can possibly even arrange remote ssh access if that would help.

By the way, since reporting, I tried compiling the SVN version of marble and rebuilding digikam against that, but it's still crashing extremely often.  I also found that an rpm build of digikam 1.7.0 crashes on startup - I reported that as bug 263786.  At first glance it looks like a different crash, but I don't know enough to be sure it's not a duplicate.
Comment 3 Marcel Wiesweg 2011-01-21 15:12:12 UTC 
One way to find out where all these threads come from is to run digikam under gdb and set a breakpoint at QThread's destructor. I have just committed a fix to 2.0 which prevent a good number of threads to be created at startup, though that's nothing bringing the application to its knees. With current 2.0 SVN, there are no more than about 10-15 threads created.

gdb digikam
br main
r
br QThread::QThread
r

for each found thread, to get a backtrace, type "bt", to continue, type "cont".
Comment 4 Martin Klapetek 2011-01-24 00:32:38 UTC 
If the breakpoint should be at QThread's destructor, shouldn't the line then be

bt QThread::~QThread ?
Comment 5 Marcel Wiesweg 2011-01-24 14:11:58 UTC 
You're quite right ;-)
I meant to write "constructor", so the debug line is right, the text not.
Comment 6 Adam Spiers 2011-01-25 11:31:35 UTC 
Thanks everyone for the gdb info.  I recompiled the kdegraphics/ and graphics/ trees into a common installation target with /opt/kde4 prefix (previously I had /opt/kdegraphics and /opt/digikam) and now I cannot reproduce the crashing, so I am marking this bug as INVALID.  It seems a bit unlikely that the common installation target would fix the crashes, but I don't think it's worth investigating further at this point (I am going to start testing the 2.0 beta now anyway).  I'll reopen if the crashes rematerialise.  Thanks again!
