Rebuilding drawtiming in maverick (against the new graphicsmagick library) did not fix the issue !

This problem is also in Debian

According to what I understand from the stack trace, the problem happens after the fontTypeMetrics call, since this seems as a valid call (according to http://www.graphicsmagick.org/Magick++/Image.html#fonttypemetrics), so I suspect that the problem is actually in graphicsmagick

REASON FOR ERROR (thanks to jwilk from pdf2djvu):

1.3.8 (January 21, 2010)
========================
[…]
Behavior Changes:

  * InitializeMagick() MUST be invoked prior to using any Magick API
    function. Failure to do so will likely lead to an immediate
    application crash. This is due to initialization and runtime
    changes intended to improve thread safety and efficiency.
    Previously it was only strongly recommended to invoke
    InitializeMagick().

SOLUTION:

In source file "main.cc" add the following line before the first while in the function (maybe there is a better place, but this one works):

InitializeMagick(NULL);

Solved semaphore.c:525 error :)

Thanks a lot ! I've just applied your patch, and it works. Also I
noticed that you've filed a bug upstream. I have just added your patch
to Debian [1], I hope to get it uploaded soon, and sync to Ubuntu from
there.
