[Bkchem-user] Error while opening file

[Sebastian \"Marduk\" Pölsterl]

Hi!

I use the latest version 0.5.1 and worked fine until I drawed a radical. 
I can draw it and save the file, but when I try to load the savec SVG 
following error appears:

<paste>
Error: 1

Is this a bug or is it my fault?
