Created attachment 159343 [details] Improved back trace I re-compiled with 'debug' use flag enabled to see if I could get any extra clues and I've attached the new back trace.
app-misc/strigi-0.5.9 is not affected by this bug.
Thanks, I'll mask 0.5.10 for the time being. Incidentally, upstream trunk is still affected by this bug, should I report it upstream or leave it to maintainer(s)?

I wonder a bit, this has occured on *all* of my systems where I tested it (3 different setups), with both 0.5.10 and SVN.
I've determined it's a problem upstream because I'm getting a segfault with the SNV version in the XML parser code. Hopefully one of the Strigi devs (or someone else) picks this up because it's been broken for a long time.
strigi-0.5* versions have been removed from the tree. Please test with 0.6.4 and if possible with KDE 4.2 as well (as i'm going to remove 4.1 soon), and close if fixed
