[Pkg-kde-extras] Bug#808734: digikam crashing when tagging faces, consuming all RAM

2015-12-22 Thread Ulrich Fürst 
Package: digikam
Version: 4:4.4.0-1.1
Severity: important
Used with SQLite database

Dear Maintainer,

I wanted to tag already found faces. That worked for some time. Then
after tagging another face digikam began to consum all the RAM.
This situation is now reproduceable by
1. starting digikam
2. tagging just one single face

I can't even close digikam at that time. Digikam takes up the whole RAM
(I tried it with up to 12 GB) and the loadavg rises up to 75 on a dualcore chip
computer. At least that's the highest I could see. 

Starting from the command line I get many times something like the
following (The numbers are changing naturally). But I get it even while
tagging something different than faces and that does work.

digikam(20782)/digikam (core): Tag 0x3521850 doesn't have a valid parent

To solve the problem I tried several things:
* Take an older database out of my backup
* Tried a new user using digikam (with the same picture files and
database)
* deleted the database, starting digikam, made a migration of an older
database). Here digikam didn't show me any pictures even after:
* Tried to update the metadata, the thumbnails, etc. from the tools
  menu.  
* started digikam with gdb
That gave me tones of lines like
