Makes me wonder if this should be a QHash<QString, bool> instead to minimize hashing and lookups?</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Summary:
The code said "unknown icons should be searched for anew each time
[so that installing new icons works]". However this leads to massive
performance issues when opening the file dialog in a dir with many
files for which there is no mimetype icon.
In my case, 293 callgrind.out.* files in one dir (it's ironic that
they would create a huge performance issue...).
To make both sides happy (installing new icons should still work, but
still unknown icons shouldn't lead to a full disk search every time
icon.isNull() or icon.pixmap() is called), let's re-resolve unknown
icons again only after 5 seconds.
Benchmark results for loading an unavailable icon :
before: 43 msecs per iteration (1897 disk locations checked)
after: 0.013 msecs per iteration (pixmap found in the on-disk cache)
And the file dialog no longer crawls to a halt in the dir with 293 callgrind files.
