Control: reassign 941557 src:texinfo 6.7.0.dfsg.2-5
Control: affects 941557 + src:gri src:maxima-sage
Control: retitle 941557 texinfo: Malformed UTF-8 character in ParserNonXS.pm

This is probably a bug in texinfo, since both the program giving the error 
(makeinfo) and the file it is complaining about (ParserNonXS.pm) are part of 
texinfo. The same error also causes maxima-sage to FTBFS at the moment. 
maxima-sage builds without changes when using texinfo from stable which is 
6.5.0.dfsg.1-4, so this is a regression.

Best,
Tobias
