[Xtightvnc] Segfault

[fzg]

Hey. I'm no X11 guru, so this is possibly an issue with Xtightvnc. Is it?

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7bd7e8f in _xdo_populate_charcode_map (xdo=0x61ba80) at xdo.c:1304
$1 = (XkbDescPtr) 0x0
$2 = 8

(gdb) where
#0 0x00007ffff7bd7e8f in _xdo_populate_charcode_map (xdo=0x61ba80) at xdo.c:1304

So we got an unhandled NULL coming from XkbGetMap() :-(

Definitely sounds like a bug. I'll try to reproduce with Xtightvnc next time I get the chance.

Jumping in this old bug... Got the issue, trace it to XkbGetMap in _xdo_populate_charcode_map returning a null pointer. I added a if that skips the for loops, it stops the crash, but things like Ctrl+Shift+T don't work. I can see a t, show up on the console though. At this point I'm stump.
