[Mediawiki-l] texvc hanging

Has anyone had a problem with texvc hanging when trying to render math 
within a wiki page?  My installation was working fine until yesterday 
when updates to pages including <math> would hang forever.  Looking at 
the processes owned by apache on the server, I can see:

sh -c convert

in addition to the other httpd processes.  Any ideas?  I've tried 
running texvc from the command line and get the following output until 
it hangs:

$ ./texvc ~/public_html/testing/ ~/public_html/testing/ 'E(C_R) = - 
\frac{1}{\log q} \sum_{i=1}^q \frac{n_r^i}{n_r} \log \frac{n_r^i}{n_r}' 
This is dvips(k) 5.86 Copyright 1999 Radical Eye Software

<texc.pro>. [1]

Several temp files are generated, ending with .dvi, .aux, .log, .ps and 
.tex.  The .ps file does look like the correct rendering of the 
formula, so I'm guessing the TeX/LaTeX piece is completing 
successfully.  Running texvc from the command line also forks a 
'convert' process that hangs.

any advice?
