Package: evince
Version: 2.26.2-2
Severity: normal
evince-thumbnailer called on a DVI file with a completely missing font
gets stuck in an infinite loop, trying to generate the TFM file again and
again. For instance, with the attached testfont.dvi , the output is
as shown below, with a backtrace below that.
It tries to generate anttb.tfm , but there is no anttb.tfm (anymore),
and no anttb.mf either. That's for the Antiqua Tornunski bold font;
there are various files like cs-anttb.tfm
evince-thumbnailer was called behind my back by nautilus, and as a result
one core was kept busy constantly in a mysterious way: no single busy
process showed in top because evince-thumbnailer kept spawning short running
mktextfm processes...
I tried to compile evince-thumbnailer from source, to add some debugging
statements (apt-get source evince ; apt-get install kpathsea-dev;
cd evince-2.26.2; ./configure; make; sudo make install),
but that self built version did correctly figure out that
the tfm file was missing.
The version of libkpathsea4 that is installed is:
