Well, if possible the people plagued by Frescobaldi crashes could try SVN of 
today (rev. 1347).

The crashes occurred when the folding marker bar (left to the LilyPond text 
input view) was hovered with the mouse, (causing KatePart to redraw the 
background of foldable parts a bit darker) while LilyPond was running, the 
document has been edited, and there has been clicked a few times on objects in 
the PDF.

KatePart contains some advanced code to translated cursorpositions to an older 
state of the document (which is used by Frescobaldi to implement smart point 
and click). The crash logs showed me that KatePart also uses this functions 
(smartRange) to highlight the text when hovering the folding marker bar.

Now I changed my code to lock this smart-interface and reset the revision to 
use each time after "translating" a cursor position (which happens when you 
click on a note in the PDF).

Hiding the folding marker bar also could end the crashes for users of current 
releases. (You can hide this bar using F9 or via Settings->Configure-
Frescobaldi->Appearance).

best regards,
Wilbert Berendsen
