G'day, Still crashes here with the following error messages: No module named serial in RS232 Source! -> continuing... No module named serial in RS232 Sink! -> continuing... Removing empty category "Custom"... >>> Verbose: Traceback (most recent call last): File "/home/wulf/projects/gnuradio/grc/src/ExecFlowGraphGUI.py", line 248, in ? exit(0) TypeError: 'str' object is not callable >>> Done The program 'Editor.py' received an X Window System error. This probably reflects a bug in the program. The error was 'BadLength (poly request too large or internal Xlib length erro'. (Details: serial 10975 error_code 16 request_code 151 minor_code 23) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) cheerio Berndt On Saturday 19 January 2008 05:38:46 Josh Blum wrote: > The error seems to come from gtk.main and not from the GRC source > itself.

Re: [Discuss-gnuradio] Gnu Radio Companion (GRC) 0.69 experience
The error seems to come from gtk.main and not from the GRC source itself. Perhaps this is the result of a race condition (in grc) between the the main thread and the thread waiting on the flow graph to finish. ->By clicking the kill button, the waiting thread finishes by calling the very same method that handles the "kill button" press. Perhaps in all the ruckus, some gtk functions get called by 2 threads at once, and eventually gtk gets upset and dies/crashes... I committed a fix for this in the GRC trunk. Can somebody with this issue try out the trunk fix and let me know? -Josh Ed Criscuolo wrote: I've seen this exact same behavior for some time.

G'day, I can confirm your observation. This is exactly my experience here too.

Frank Brickle used GRC for our SDR class design lab. It was a success. I cannot comment on the crash.
