Lazily create the desktop files for appinfos created by
2008-01-29 Alexander Larsson <alexl@redhat.com>
* gdesktopappinfo.c:
Lazily create the desktop files for appinfos created
by g_app_info_create_from_commandline() when needed
for mime associations. This allows run-time use
of GAppInfo object without creating unnecessary
files on disk.
