Enormous image cache

[lusepuster]

Partly by chance, I discovered that Gwibber has saved an enormous image cache in my ~/.cache/gwibber/ directory. By doing a rm * in the directory, I got the error "/bin/rm: argument list too long" ! think that is the first time in my *NIX life I encountered this. Upon a rm -rf on the entire directory, I found almost 1½ GiB of disk space freed.
 Unfortunately, I cannot tell if this has happened before or after my upgrade to Gwibber 2.0.
