Comment 1 caulier.gilles 2014-06-14 21:57:51 UTC

This crash have been probably fixed in 4.0.0 release where a lots of improvements have been done into Import UI.

Please try again with this new release.

Comment 2 Christopher Yeleighton 2014-06-19 10:00:23 UTC

I tried 3.5 once more and it did not crash this time, so it would be inconclusive anyway.

Comment 3 caulier.gilles 2014-06-19 11:50:33 UTC

The right digiKam version to check is 4.0.0 released few week ago.

Please consider to update and try again...

Gilles Caulier

Comment 4 Christopher Yeleighton 2014-06-25 09:56:17 UTC

Since version 3.5 did not crash the second time I tried, there is no point in checking that 4.0.0 does not crash either, or is there?  Unless anything unexpected occurs, the update is on my distro.
