There are a number of places where the default behavior of a widget in 
maemo is different from that of stock GTK.  There are bugs filed against 
many of these misbehaviors in bugzilla, but so far the answer has been 
that the "bad" behavior is implemented according to Nokia spec and won't 
be fixed.

It's not a big deal if you're writing an application from scratch 
(except that it can be confusing debugging across platforms), but does 
increase the effort involved in porting existing apps.

You can find the known bugaboos regarding gtkcellrenderer by searching 
for it in maemo's bugzilla.
