the last bt says it all:

e is asking the xserver for something. the xserver is not responding. likely
because some client grabbed the xserver. if e grabbed it... then this would
work because the client grabbing the server has exclusive access. all other
clients are locked out during a grab.

so... some client has grabbed x. it isn't e that has done it. well not the x
connection it controls and uses. it's some other connection. my guess is that
something that that perl script runs is grabbing the xserver... and not
ungrabbing it. check the processes in that tree and maybe kill them and see. if
you kill those processes in the pl tree possibly perl is the only process). if
things work again, then i'm almost certain your problem is over there with that
script/tool and what it does. there is nothing e can do about it as it's been
locked out by those tools along with every other x client.

as a separate thing if e can't fork... fork() is likely fialing - that's a
system call. is ulimit or some security thing causing e to have a limit on the
number of child processes? too many processes?

Is there a mistake in this desktop file ?

Desktop Entry]
Name=GenTOLpatch
CExec=perl /var/d/TOLutils/GenTOLpatch/exec.pl
Icon=GenTOLpatch
Comment=GenTOLpatch
Terminal=false
Type=Application
Categories=Utility;

knowing that "perl /var/d/TOLutils/GenTOLpatch/exec.pl" works ok.

where is e blocked? go to a text console and:

killall -SEGV enlightenment

you'll get your usual crash handler + ~/.e-crashdump.txt and that backtrace
might help.


Thank you, I am not able to read (it is in 
www.tol.fr/download/e-crashdump.txt ).


But I have tried to simplify the problem by clicking in the ibar icon at 
the beginning of the session.
It does block no more but I get a message  "Enlightenment was unable to 
fork a child process".


So my question is now, why I success to excute 
"/var/d/TOLutils/GenTOLpatch/exec.pl" in terminology and not from the 
ibar icon ?
