pybliographic refuses to accept new entries

Hi list,

What can be wrong with my pybliographic (1.2.5)? Sometimes the programme 
refuses to accept new data. I just opend it to insert two new items to my 
bibliography file. One worked without problems. The second one could not be 
applied, also the editing of native didn't work. Simply nothing happened when 
I clicked one of the two buttons. All I could do is to cancel the new entry, 
and my data was lost. This happened before, but only from time to time. I 
edit BibTeX files with pybliographic and run Suse 9.3.

Can anybody tell me what the mistake or bug could be?

Thank you very much,
Sven
