More likely (since no one's reported anything recent - Ubuntu's
xterm is from last summer) is this item fixed in patch #263:
Patch #263 - 2010/10/13
corrected initialization of "misc" resource values, to ensure that xterm has allocated a copy of strings which may not have been malloc'd by the X library (Debian #600129).
It's unlikely to be the same bug.
