dockbarx crash: mask has no attribute 'scale_simple'

[Eemil Lagerspetz]

Hi, on Lucid, Dockbarx crashes on me pretty randomly:

Actually, this may be because my theme, human_bar, uses a mask which is not defined. I corrected the mask in the theme file, and will now wait for this crash again.

The crash has still occurred:

Another bug I haven't answered?

Does this still exist with x.0.30? If so, could you post the error again, so I get the correct row number?

[Eemil Lagerspetz (eemil-lagerspetz)]

This bug was caused by a mask name being misspelled in the theme file for human bar at one point. The resulting mask name was used instead of the mask so this is why the error refers to 'str'.
However, the error should be avoided somehow, for example by using an empty/full/default mask in this case, and printing an error that users can understand.
I will now bork the theme similarly and see which error pops up.

I see this is _still_ marked as new. And I can't remember if I did anything about this one or not. Is this bug still there?
