Segfault in active Serial Interface

[kop316]

Hello!

When I have an active serial interface, after some amount of time, I get a segfault. When I look at the fault handler, I get this:

Fatal Python error: Segmentation fault

We don't have anything that's not pure python, so I don't think this can be an issue with this library directly. The current thread noted there is in some GTK code, which seems like the most likely issue to me -- pyserial is also, from what I can tell, not using any C extension modules. I guess there's also the possibility it's in the Google protobuf library that's noted in the list of extensions, but I'd definitely look at the GTK/GIO code first.

Hello!

Sorry it took me a while to get back to you. Thank you for the info! I agree, I think there was a bug in GTK. I appreciate the feedback!
