[GNC-dev] segmentation fault / gnucash crashing upon using online banking actions

Tue Oct 15 06:10:07 EDT 2019

As derek already said: you are using a system-installed gwenhywfar. You need to check at aqbanking configure time that it really chose the correct libgwenhywfar, and gnucash subsequently too.

Thanks!
