dia problems with czech characters

[clock atrey karlin mff cuni cz]

Hello

When I compile dia and install and then try to make text labels with Czech characters,
the editation of the text behaves strangely. Czech characters are replaced for
various ASCII ones and spaces. Pressing áááččččdddd yield
ááádddd____ where _ is a space instead of "č", chracters are written not
on the end and after deleting such strange text, pieces of characters remain
and the cursor gets multiplied. 

System insformation included in attachment.

I have tried to compile dia on another computer with (prbably) the same
versions of all necessary libraries and it works. It works also when I access
the computer remotely from my X.
