Title:
Fix crash when opening DepCache before Cache
Status in apt package in Ubuntu:
Fix Released
Status in apt source package in Trusty:
Fix Released
Bug description:
[Impact]
apt search and probably other code crashes some time, as GetDepCache() in
trusty does not call BuildCaches() first.
[Test case]
Run apt search -o RootDir=/dev/null foobar, make sure it does not crash.
[Regression potential]
There may be some locking implications, as we build caches when opening
depcache first, without locks. That said, the same code is in use in all
post-trusty releases, and they work fine.
