#25 Kchmviewer can't open any chm file, LCID error

I'm unable to open any chm file, every time I get:
Could not detect text encoding by LCID

And then program exits.

I've experimented this bug with debian unstable package
and also with a custom build of version 2.6.

I'm running a debian unstable on a powerpc machine.

Help me, I don't want to use xchm! :D

Thanks in advance
