Comment 13 for bug 1460386

Ok, let's try another approach. I've collected full execution trace of zim with problem notebook:
python2 -m trace --timing --ignore-dir=/usr/lib/python2.7 --trace /usr/bin/zim --standalone -D 'Test sourceview hanging'

hang_trace.txt is the part of the trace which is spewed in console upon clicking on hanging page in index tree.
