xsuspender 1.3: xsus_window_suspend: assertion failed: (! xsus_entry_find_for_window_rule (window, rule, suspended_entries))

[Self-Perfection]

xsuspender at my system crashed once with following message

**
xsuspender:ERROR:./src/xsuspender.c:145:xsus_window_suspend: assertion failed: (! xsus_entry_find_for_window_rule (window, rule, suspended_entries))
Bail out! xsuspender:ERROR:./src/xsuspender.c:145:xsus_window_suspend: assertion failed: (! xsus_entry_find_for_window_rule (window, rule, suspended_entries))

Probably it was triggered by opening one more window for the app that xsuspender tracked.

I understand this report contains too little details to be useful. I'll try to collect more data if it happens again.
