I have this problem as well. I've traced it and discovered that
vim sends the special CSI sequence `ESC[>c' and it gets from mrxvt the
following response: `ESC[>82;0.5.3+25;0c'
Than I looked into vim's code (term.c):
if (*T_CRV != NUL && ((tp[0] == ESC && tp[1] == '[' && len >= 3)
|| (tp[0] == CSI && len >= 2)))
{
j = 0;
extra = 0;
for (i = 2 + (tp[0] != CSI);
i < len && (VIM_ISDIGIT(tp[i])
|| tp[i] == ';' || tp[i] == '.'); ++i)
if (tp[i] == ';' && ++j == 1)
extra = atoi((char *)tp + i + 1);
if (i == len)
return -1; /* not enough characters */
/* eat it when at least one digit and ending in 'c' */
if (i > 2 + (tp[0] != CSI) && tp[i] == 'c')
{
[ snip ]
}
}
I didn't debugged it, but it seems to be quite obvious that vim except
the response to contain only digits, comas and semicolons, and it fails
on `+' character.
I tried to find out what characters are valid in the response, but the
only site I found (http://invisible-island.net/xterm/ctlseqs/ctlseqs.html)
says only:
CSI > P s c Send Device Attributes (Secondary DA)
[ snip ]
??? CSI > P p ; P v ; P c c
and P v is the firmware version (for xterm, this was originally the XFree86
patch number,
starting with 95).
Anyway vim should probably skip all unknowns charaters until it finds the ";c"
string, so I'm cloning the bug for vim.

robert
