Sorry for the delay, the bug only hit me a few times since I reported it and lasted only for a few seconds (at least after I discovered it). But now it happended again. I have: [EMAIL PROTECTED]:~$ apt-show-versions | grep 'libx.*-dbg' libx11-6-dbg/lenny uptodate 2:1.1.4-2 libxcb1-dbg/lenny uptodate 1.1-1.1 and here it happens: [EMAIL PROTECTED]:~$ xcalc No protocol specified Error: Can't open display: :0.0 [EMAIL PROTECTED]:~$ echo $DISPLAY :0.0 [EMAIL PROTECTED]:~$ gdb xcalc GNU gdb 6.7.1-debian Copyright (C) 2007 Free Software Foundation, Inc.

Should I do anything special with GDB?
