Bug#627654: evince and evince-thumbnailer hang on DVI file with (missing) CJK fonts

[Manuel Bilderbeek]

Package: evince
Version: 2.30.3-3
Severity: normal

After browsing a directory wich contained a dvi file with CJK fonts
(which are apparently missing, see below), a process evince-thumbnailer
kept hogging the CPU.

I noticed at some point that some process was eating 40% of the CPU
time. Top didn't really reveal what it was. It appeared to be
evince-thumbnailer that kept eating this CPU time, because when I killed
it, I saw the CPU usage going to 0.

When viewing this dvi file with evince, I get a lot of output like this:

kpathsea: Running mktextfm dmjkata
mktextfm: Running mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input dmjkata
This is METAFONT, Version 2.718281 (TeX Live 2009/Debian)


kpathsea: Running mktexmf dmjkata
! I can't find file `dmjkata'.

! Emergency stop.

grep: dmjkata.log: No such file or directory
mktextfm: `mf-nowin -progname=mf \mode:=ljfour; mag:=1; nonstopmode; input dmjkata' failed to make dmjkata.tfm.

After installing the latex-cjk-japanese-wadalab package, everything
works fine again.

So, it seems evince hangs up eating a lot of CPU time if it encounters
files that requires fonts that are not installed.

If necessary, I can provide the file that gave the above output.
