   Looks like this may be related to cairo. I've gotten a similar error trying to run Clock.hs
   :-/

   One thing also is that the Homebrew gtk package wants its own cairo dependency even though MacOS X ships with a cairo of its own. The cairo brew claims the system one is too old.

   If you cabal install cairo you get the older system one.

   I get a crash both with the older one and the Homebrew cairo linked in (I think)

   Oh, the Clock.hs refers to the gtk2hs directory.

   Also a C hello world for Cairo seems to run

   Seems not be threadscope-specific at all, so have filed http://hackage.haskell.org/trac/gtk2hs/ticket/124

   Note that this may be a blocker for anybody using a newer Mac

   Thank you for the report. I've never encountered this on Linux/amd64, whether with TS or other programs. BTW, the gtk2hs ticket URL is actually http://hackage.haskell.org/trac/gtk2hs/ticket/1241

   The following report by Ben Lippmeier seems to be related:

   Threadscope segfaults randomly on mac. I installed gtk via homebrew and
   then followed the instructions on the wiki. It's *just* stable enough to
   use, but crashes every few minutes, which is very frustrating.
   
   It crashes randomly just when I'm scrolling the plot.
   
   When it starts up it complains:
   
   desire:ray benl$ threadscope gloss-ray-interleave-800x600-N7.eventlog
   Xlib:  extension "RANDR" missing on display "/tmp/launch-Bn2zDn/:0".
   
   (process:27518): GLib-GObject-CRITICAL **: gtype.c:2712: You forgot to

   call g_type_init()
   
   (threadscope:27518): GLib-GObject-WARNING **: cannot retrieve class

   (process:27518): GLib-GObject-CRITICAL **: gtype.c:2712: You forgot to
   call g_type_init()
   
   (threadscope:27518): GLib-GObject-WARNING **: cannot retrieve class
   for invalid (unclassed) type `<invalid>'
   
   ... so I expect it's writing to unallocated memory.

   To which Edsko de Vries replied:

   FWIW, none of those errors appear when I start threadscope
   on my Mac (gtk+ 2.24.9, gtksourceview-2.10.5, compiled manually
   direct from source). (I'm not getting crashes either
   but that probably doesn't mean much as I don't often use threadscope).
