Segmentation fault when opening local pool

[trembel]

When I try to open my local pool, I get a segmentation fault.
Version: horizon-eda 2.6.0-2, installed using AUR.

Backtrace (from gdb):

Needs more info. Does this happen with other pools, also with a new empty pool? Did this start happening out of the blue?
