Description Michi 2010-05-19 09:30:20 UTC
Version:            (using Devel)
Compiler:          gcc 4.5 
OS:                Linux
Installed from:    Compiled sources

Hi,

I guess since strigi 0.7.2 I have a problem with indexing pdf files. Whenever the indexer hits a pdf it hogs up one cpu core and simply hangs.

When I do a manual run with strigicmd, I get something like the following log message:

'' is not a UTF8 or latin1 string
Error in parsing: Keyword obj not found.

That's when the process starts hanging.

I think I have the same problem here in KDE SC 4.5 compiled from trunk on 2010-06-05. When I check the process list I see "/home/kde-devel/kde/bin/nepomukservicestub nepomukstrigiservice" using all the CPU. I attached to it with GDB and got this backtrace:

Can't fix this unless I have a copy of the file in question :(

Actually it was almost any pdf. And indeed it _was_, because since 4.5 release the problem has simply vanished.
Comment 4 Sebastian Trueg 2011-01-05 18:31:59 UTC
Closing as fixed due to the last comment about 4.5
