Bug#421523: uxterm: segfault when trying to use "Font|selection" menu entry
Package: xterm
Version: 225-1
Severity: normal
While playing around trying to understand how uxterm works, I
discovered the "selection" item in the "font" menu, and played with it
before realizing it was a generic xterm feature documented in the man
manpage.
When selecting random latin characters (eg. from the prompt, either in
plain xterm or uxterm), sometimes I get the selection apparently
turned to "black on black" (I am using "white on black" for nomal
text), but sometimes it just segfaults, gdb reporting:
(gdb) bt
#0 0xb7d0736c in XDrawImageString () from /usr/lib/libX11.so.6
#1 0x08076de0 in ?? ()
#2 0x0809a358 in ?? ()
#3 0x01a00013 in ?? ()
#4 0x00000000 in ?? ()
With uxterm it gets better when selecting CJK characters pasted from
another app (precisely, from firefox browsing
http://fr.wikipedia.org/wiki/Sh%C5%8Dgi, any string I tried,
eg. \u738b\u5c06): I get the following crash backtrace from xterm
itself (also note the final "Aborted\n" trunkating the output).
