Maybe the plugins should be enabled instead of disabled by default? Or we could add a default enabled/disabled setting in the .desktop files' metadata.

Also, after enabling some plugins, I get a crash on shutdown, and on restarting the last plugin I enabled isn't loaded:

Exception ignored in: <module 'threading' from '/usr/lib64/python3.4/threading.py'>
Traceback (most recent call last):

File "/usr/lib64/python3.4/threading.py", line 1283, in _shutdown
  t = _pickSomeNonDaemonThread()
File "/usr/lib64/python3.4/threading.py", line 1290, in _pickSomeNonDaemonThread
  for t in enumerate():
File "/usr/lib64/python3.4/threading.py", line 1260, in enumerate
  return list(_active.values()) + list(_limbo.values())

KeyError: 'tenscripts'

Then on starting and closing Krita again, I get an assert:

Oops! Looks like I accidentally merged the wrong version. It should be fixed now.
