Could you reproduce the problem? If yes, please try as soon rc1 is out if this
bug is fixed for you.

digiKam 1.0.0 is out since few days...

http://www.digikam.org/drupal/node/491

Please try with this version coming with more than 400 bug-fixes.

Thanks in advance

I'd assume this is fixed?

With the new report for 1.0.0, it seems this bug is not fixed. I have no idea why.

A metadatahub keeps a map of TAlbum pointers.
For a good long-term solution, we need to get away from TAlbums*, they cannot be accessed from a different thread and cause these problems here. We probably need an additional cache of the tags tree, at a low level (AlbumDB, DatabaseAccess), and fully mutex protected. It needs to provide tag id -> tag path, tag path -> tag id, tag name -> all tag ids with that name.

digiKam 1.1. release will be done in few days. Please check if this entry still valid.

Thanks in advance

SVN commit 1091832 by mwiesweg:

For the time being (until there is a thread-safe tag cache at a low level)
we must look after the MetadataHub and notify it when tags are removed.
This code was already added for 1.0, got lost during the model/view merge, but
we got crash reports for 1.0-beta5, 1.0.0, 1.1.0, and 1.2.0-svn.
So I cannot be sure that this fully fixes 214340.

digiKam and Kipi-plugins 1.2.0 are out. Please check if crash is still valid there.

Thanks in advance

Comment 13 Marcel Wiesweg 2010-04-12 18:22:39 UTC
In current SVN, the ImgDescEditTab has been ported to use the new TagsCache. No storing of TAlbum pointers anymore, this crash must be fixed.
