Subject: Fix Bug 584390: Cache doesn't work on first run
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e4df9b62c6ec3a285fcec005f5cf163e2d07cf75;p=libchamplain

Fix Bug 584390: Cache doesn't work on first run

It turns out that the ~/.cache/champlain didn't exist
at the moment of the first cache request, resulting in
a error when creating cache.db which would later result
in more errors from SQLite preventing the cache from working.
