MimeType issues on CI (Was: Re: Delaying KF 5.21)

[Daniel Vrátil]

Hi David,

I've been debugging similar failures in Kevin's Zanshin tests with Ben and 
eventually tracked it down the same mime database problem.

Turns out when you include /usr/share in XDG_DATA_DIRS, all mime types that 
might have been provided by other dependencies in /srv/jenkins/.../foo/inst/
usr/share/mime are ignored, possibly due to update-mime-database not being ran 
for those directories.

I manually ran update-mime-database on the akonadi and kdepim-runtime install 
dirs on Jenkins and the Zanshin tests magically started passing again.

Our idea for a quick dirty fix was to simply run update-mime-database once CI 
sets up the environment variables but before the test is executed.

David, do you have any better suggestions?
