digikam (3.5.0) on KDE Platform 4.11.3 using Qt 4.8.5

Selecting a picture with a wrongly recognized face, clicking on the wrong tag,
and entering the proper name,

Some ten or twenty seconds later, Digikam will inevitably crash. Up to then, it
consumes all available virtual memory of the OS.

--- Comment #13 from Michal Sylwester <[hidden email]> ---
I'm having some similar crashes when working face tags, and I'm also seeing
same behavior as Christian. After tagging a face digikam starts eating up
available memory until it's killed by kernel. I wasn't able to gather any logs
while it was happening though.

I suspected that this may be related to asking digikam to write the face
information to image metadata (I have more problems when marking several faces
at once), but setting this to off made no difference, at least for the memory
consumption issue.

Digikam 3.5 on current ubuntu saucy, everything from current packages except
for digikam.

--- Comment #15 from Michal Sylwester <[hidden email]> ---
I tried to find out more (this problem makes face tagging unusable for me...),
and I'm just more confused now. But perhaps someone can make something out of
this...

I tried to use a combination of kDebug() and attaching gdb to the "hungry"
digikam process to try to figure where exactly it's getting stuck. I've got a
backtrace that is rather different from any posted here in the bug reports.
Unfortunately I wasn't able to get DrKonqui generate another report for me this
time.

Backtrace from the stuck thread:

Some more playing around indicated that most likely cvWriteRawData (#4) never
exits. This could indicate wrong usage or bug in opencv.

If someone would like to reproduce this, here is what I did:
1. Disable swap: swapoff -a  (this gives less time to start gdb before digikam
is killed by kernel, but system won't get unresponsive, may be good to wait a
little afterwards for system to stabilize)
2. Start Digikam
3. Tag some face from "Unknowns"
4. Use htop to figure out the cpu eating digikam pids (I had 2)
5. Attach gdb to one of them: gdb --pid=12345 (had to run this as root)
6. Show backtrace: bt
7. Bonus: try to find on which function digikam is stuck: next many times until
it won't get back to prompt anymore

That's all I know, hope this helps someone...
