[pmwiki-users] Searchbox and nice urls bug

[Athan]

Just noticed the following problem, reproducible on pmwiki.org

Go to http://www.pmwiki.org/wiki/PmWiki/PmWiki or any other pmwiki page
On top searchbox, simply click Go (no need to enter something)
Results pagelist is displayed as 
http://www.pmwiki.org/wiki?n=PmWiki.PmWiki&action=search&q= (not a ...nice 
url)

Now go directly to searching page  http://www.pmwiki.org/wiki/Site/Search
Click "Search" button (no need to enter something)
This time, the results pagelist is using nice url 
http://www.pmwiki.org/wiki/Site/Search?q=&action=search

Any idea how this can be fixed ?
