Hi, is that not a normal enlightenment (window manager) error message? I think it will be useful to start the script from the command line. Then you get the error output directly from the python interpreter. with kind regards Patrick Beck Am Montag, den 28.12.2009, 20:39 +0100 schrieb Ivo van den Maagdenberg: My python app ends regularly with a segmentation fault and offers to save a log by means of a gtk dialog.

I think it will be useful to start the script from the command line. Then you get the error output directly from the python interpreter. enlightenment pops up these dialogs whenever a child it is tracking (that it would have exec'ed) exitsabnormally. either non-zero exit codes (this is meant to imply an error at the higher levels of the app - missing file, missing config, etc. etc. but the app exits with a non-zero exit code) or exits where it died due to a signal (segfault, abort etc.) e also nicely is capturing stdout and stderr and will provide that for you if it has any so maybe the app went help! no config! on stderr and then exit(-1)'ed). this is what you get as opposed to the window mysteriously vanishing and you process having vanished and you have no idea why.

The downside of this all is that I will have to have a GPS fix, which will force me to go outside in wintertime :/ you don't need a whole session from the cmd-line, just tun your app from it under gdb (yes it is installable on the device if your oe repositories are complete enough - or you use debian). i.e. just ssh in, then export DISPLAY=:0 to work on the local display and run app and debug as u would anywhere on linux on a desktop. (sshing in just gets you a sane kbd and desktop screen to use as your debug console :)) -- - Codito, ergo sum - I code, therefore I am -- The Rasterman (Carsten Haitzler)ras...@rasterman.com ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
