Description Stephen 2011-09-30 11:21:33 UTC 
Application: digikam (1.9.0)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Large image collection NFS drive, although database is local. I get this message on console: "KGlobal::locale::Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work 
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
KCrash: Application 'digikam' crashing...
"

Had been working fine until last major Ubuntu upgrade.

The crash can be reproduced every time.

Comment 1 Marcel Wiesweg 2011-10-07 17:26:00 UTC 
Memory allocation fails when listing a directory in QDir::entryInfoList. This would usually indicate out-of-memory condition, or rather a memory request which cannot be fulfilled. How many files are involved?
Comment 2 Stephen 2011-10-08 18:58:42 UTC 
Just under 6000.

I  get 15 secs of network traffic, cpu goes 100% then over the next few minutes the memory is all used up (2G).

I will try on a machine with more memory.
Comment 3 Stephen 2011-10-09 10:55:06 UTC 
Tried with a machine with 8G and got this:


KGlobal::locale::Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work 
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in use, all queries will cease to work.
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Comment 4 Marcel Wiesweg 2011-10-09 14:28:17 UTC 
Then indeed something is eating memory, and there is no good reason for that. If it worked with previous linux distros and same digikam version, chances are this is a bug somewhere in the system stack (Qt, file system, NFS driver)
Comment 5 Stephen 2011-10-21 10:54:38 UTC 
Upgraded to Ubuntu 11.10 and problems has gone.

Thanks.
