I haven't looked deeply into this, but several sources suggest that this error might be caused by a Tk that is compiled without thread support. You can check if the Tk your Tkinter uses supports threads with: $ python Python 2.6.6 (r266:84292, Dec 27 2010, 00:02:40) [GCC 4.4.5] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from Tkinter import * >>> root = Tk() >>> root.tk.call('info', 'exists', 'tcl_platform(threaded)') 1 >>> Apparently, if this call returns 0 instead, threads are not suported. I also found the following example: http://stackoverflow.com/questions/14521319/tkinter-threads-exception-out-of-stack-space-infinite-loop where the same error message was caused by a buggy implementation of threads in a Tkinter app (they tried to call mainloop() from a child thread there, which is certainly a bad idea ;) , so from the little I know I would not bet my savings that the app in question is innocent either; maybe you can look through their code, in case the application is not too complex, to make sure that none of the program's child threads does touch Tk (something that should be avoided at any rate because it will make the app behave more or less unpredictable)?
