One of the things that's always given me a bit of headache is that Tk of 
course isn't a Python project, and it's sometimes hard to keep track of 
how well tkinter isolates you from its particular weirdnesses - Tcl is a 
different language, after all.  My memory is that in referring to 
bitmaps in Tk, you need a special leading character to indicate what 
you're passing is a filename, and not a variable already containing the 
bitmap contents.  The error message *sounds* like that case or I 
wouldn't mention it, but I'd be kind of surprised if tkinter actually 
made you follow that convention. (the magic character in Tk, which I had 
to spend some time in long long ago - let's just call it "last century" 
for grins - is an '@' unless my memory has failed me, which is eminently 
possible).
