After switching from 0.6.8 to 0.7.0b3 (sqlite backend)
I have trouple with topics that start with a number,
e.g. "8C-PTR"

If I select "8C-PTR" as topic and submit the changes I
get the error message:

 invalid literal for int(): 8C-PTR

Topics starting with a letter work as before. If I
rename the topic from "8C-PTR" to "A8C-PTR" the error
disappears. Changing the name back to "8C-PTR" restores
the error.

Any ideas?
