My attempts at bisecting were an utter failure. First I had problems building
after using bzr bisect so I decided to bisect "manually". I was able to easily
reproduce the problem with some revisions e.g. 108034 by repeatedly exporting
an org file to pdf (only required 3-5 exports). I was unable (after 10-15
exports) to reproduce the problem with other revisions e.g. 108049. I had to
leave it though, and now that I come back to it I can't reproduce the problem
with revision 108034. So there's something weird going on.
FWIW I was trying to bisect "backwards" by finding the revision where it was
fixed for me. There were far fewer commits that way since I hadn't previously
updated for about a month.

That's good to know. But `valgrind ./emacs` wouldn't work I assume? Anyway,
I'll try it later if I can reproduce the error.
