Always need package versions. python2-pyqwt? python2-pyqt4? qwt5? sip? python2-sip?
Comment by Johannes Koch (darkforce) - Wednesday, 03 May 2017, 15:02 GMT
Sorry, I thought I had it written in the subject. It's python2-pyqwt 5.2.0-2.

/* edit: Here are the dependencies as well:
python2-pyqwt 5.2.0-2
python2-numpy 1.12.1-1
python2-pyqt4 4.12-4
qwt5 5.2.3-4
sip 4.19.2-1
python2-sip 4.19.2-1 */

OK, so it's not the issue I was wondering about. sip 4.19.0 had issues with segfaults very similar to this.

I think I had the similar error with gnuradio. When I ran gr_filter_design, segfault occurs with stacktrace.

Pushed a rebuild of python2-pyqwt 5.2.0-3, does this fix the issue?
Comment by Johannes Koch (darkforce) - Tuesday, 29 August 2017, 10:53 GMT
Yes, that fixed it for me. Thank you!
