I just completed a Copy/Paste from geany to gnome terminal during an svn commit 
in one directory, then I opened another file in a different directory to edit 
it.  One was gcc/fortran/ChangeLog the other was gcc/testsuite/ChangeLog.  I 
recall that I ran svn update on that second file to make sure I was editing the 
latest version.  That would mean the contents got changed while geany had the 
file opened.

I suspect the gtk guys need to do

Yes I did build it.  gdb/dwarf obviously does not like it. :)

Yes,, this looks like a GTK bug. Anyone here have comment rights on that 
bugzilla already and could post this info their? Otherwise, I have to go set up 
yet another bugzilla. :)
