I think there was an over-enthusiastic cleanup. The previous version of default.py had these lines near the top of _get_settings (around line 349)

try:
self.minwidth = int(__addon__.getSetting( "minwidth" ))
except ValueError:
self.minwidth = 0
except Exception, e:
log( 'unexpected error while parsing last.fm width setting' )
log( e )
self.minwidth = 0
try:
self.minheight = int(__addon__.getSetting( "minheight" ))
except ValueError:
self.minheight = 0
except Exception, e:
log( 'unexpected error while parsing last.fm height setting' )
log( e )
self.minheight = 0

Putting them back into 1.5.7 version fixes the problem for me.
