An anonymous tester reports a crash upon opening the debug log dialog (via Menu -> "Help" -> "Export Debug Information..."). My attempt at reproducing locally shows the following:

Traceback (most recent call last):
  File "/home/user/gridsync/gridsync/gui/debug.py", line 105, in load
    filters = get_filters(self.core)
  File "/home/user/gridsync/gridsync/filter.py", line 93, in get_filters
    filters.append((core.executable, "TahoeExecutablePath"))
AttributeError: 'Core' object has no attribute 'executable'
zsh: abort      gridsync --debug

This appears to be fallout from the switch to new-Magic-Folder (which also removed the Core.executable attribute when dropping the requirement on Tahoe-LAFS 1.14). Given that this bug crashes the application in its current state and makes further debugging difficult for users, fixing it should be considered high priority.
