[Idesk-users] floating point exception

[niels v. h. <kr...@us...>]

hi,

i'm fairly new to idesk, but i can already say it's a great addition to 
my windowmanager (kahakai).  i've encountered an error from time to time 
however.  i use some icons to control xmms playback (forward, rewind, .. 
the basics) but sometimes i get a floating point exception after 
pressing one of those icons, after which idesk exits.

can somebody tell me what's causing this?  or is this already a known 
bug?  i'm running Fedora Core 1 (x86) and as mentioned, i'm using 
kahakai (kahakai.sourceforge.net) as my window manager.  i've set idesk 
to start in my .xsession, before starting up kahakai.

regards,

Could you tell me what version of idesk you are running? Is this
happening to all your icons, or just a few specific ones? Could you post
one of the infringing icon files?

the xmms "control" icons are all similar to this:

table Icon
    Caption:
    Command: xmms -p
    Icon: /home/niels/.icons/play.png
    X: 956
    Y: 751
end

i haven't had this error with the other icons, but i've only got two
others (so far), for rebooting and shutting down, so i don't use those
that much.

and i'm running idesk 0.5.5, made from source.

thanks for the soon reply!

maybe you can start it under control of gdb (building with debugging
code) and then provide backtrace, core file and strace output.

I guess this would help, to track down the problem.

i've done so, and here's the backtrace (attached).  i assume i've done 
it correctly (the backtrace part at least), as i'm not familiar with 
gdb.  if more information is needed, i'd be more than willing to provide 
it if someone could explain me on how to get it.

regards, and thanks for the help ..

Ok, thanks for that. It looks like if you have a SnapWidth or SnapHeight
of 0, then you can get this error. Whats happening is that you are
modding (the modulus operator something by zero, which causes a divide
by 0). Do you have those options set in you config file? Let me know if
the problem is fixed by having those options be set to non-zero values.

I'll make sure to patch this for next release, if it ever gets finished
:(.

indeed, they both had values of 0.  i'll let you know if idesk crashes 
again with non-nil values!

thanks for the help!
