retitle 484819 kazehakase: doesn't (always) work over ssh tunnel
thanks
Hi,
this is getting more strange.

The ssh client machine where it didn't work remotely was "snitch", a
workstation with three monitors. The lenny machine where kazehakase
runs is "nemo", an EeePC.
Same situation, but this time my ThinkPad "c-crosser" as ssh-client:
ssh from an Etch amd64 machine with Etch's openssh-client to the very
same lenny machine "nemo" -- and it works. Both ssh client machines
use FVWM with the nearly same configuration.
Differences between the two client machines: Multihead display on
snitch, single display on c-crosser, different kernels (both
self-compiled vanilla kernels, 2.6.23.16 on snitch, 2.6.24.4 on
c-crosser), connection between snitch and nemo was twisted pair
gigabit ethernet, the connection between c-crosser and nemo is WLAN
(but in theory that shouldn't make any difference).
Strange thing on c-crosser though: If I exit kazehakase using Ctrl-Q
the window vanishes, but the process keeps running. Ctrl-C (kill -INT)
can't stop it. Ctrl-\ (IIRC a kill -QUIT) does.
strace on kazehakase after the window closed:

... and so on, always hanging a "poll(" for a few seconds.
BTW: If I try that from c-crosser with ssh to "visa", a Debian
GNU/kFreeBSD (kfreebsd-i386) machine with Sid, and start kazehakase
there, it segfaults. (But this is probably another bug, probably
kFreeBSD related -- and I haven't tried kazehakase locally yet on that
architecture.)
Tell me, if you need more information.
