[LON-CAPA-admin] Ubuntu 10.04 and Mimetex

[Michael Stern]

Hi,

our installation of LON-CAPA 2.10.1-2011113023 on Ubuntu 10.04.4 LTS (64bit)
has a problem rendering formulas with mimetex 1.70.
The expression
https://lc.fh-stralsund.de/cgi-bin/mimetex.cgi?$a+b\mbox{~~,~}c$ does not
work as expected.
On various CentOS systems with the same mimetex version we got the correct
result, but I found the same behavior on
https://proteus.physics.ndsu.nodak.edu/cgi-bin/mimetex.cgi?$a+b\text{~~,~}c$
(probably another Ubuntu installation).

The error occurs only with {~~,~} and {~,~~}.

Are there any known problems related to Lon-Capa under Ubuntu in this
context?
 
Thanks
Michael Stern
