Version First unspecified

OS: Linux
Status: REPORTED

DESCRIPTION
On MIME updates (updating desktop application with mime/desktop data)
kglobalacceld starts refreshing application shortcuts, which results in
KBuildSycoca::recreate() call from kwin context.
This blocks screen updates, even the mouse cursor.
STEPS TO REPRODUCE
1. touch /usr/share/mime/packages/
2. update-mime-database /usr/share/mime
3. wiggle the mouse while it's updating
OBSERVED RESULT
Mouse cursor locks
EXPECTED RESULT
update-mime-database does not influence screen repaints
