Playing a file that has accents in its name (need not be Unicode;  any ISO-8859-1 high half character will do) writes its URL to share/apps/kmplayer/recent.xml.  On every subsequent run of kmplayer, the representation of that URL appears to be corrupted.  After a few more runs, the file approximately doubles in size every time and soon affects the startup/shutdown performance of kmplayer.  This problem perists without limit until the recent.xml file is removed.

Starting with an empty file, after playing one media file with a single accented character in its name (file pathnames shortened):

<playlist>
 <item url="/d/23 - Der Maulwurf in der WÃŒste.avi"/>
</playlist>

After playing another file:

<playlist>
 <item url="/d/25 - Der Maulwurf auf dem Karneval.avi"/>
 <item url="/d/23 - Der Maulwurf in der WÃ<83>ÂŒste.avi"/>
</playlist>

After playing a third file:

<playlist>
 <item url="/d/33 - Der Kleine Maulwurf und die Freundschaft.avi"/>
 <item url="/d/25 - Der Maulwurf auf dem Karneval.avi"/>
 <item url="/d/23 - Der Maulwurf in der WÃ<83>Â
<83>Ã<82>ÂŒste.avi"/>
</playlist>

After a fourth file:

<playlist>
 <item url="/d/28 - Der Maulwurf und die Medizin.avi"/>
 <item url="/d/33 - Der Kleine Maulwurf und die Freundschaft.avi"/>
 <item url="/d/25 - Der Maulwurf auf dem Karneval.avi"/>
 <item url="/d/23 - Der Maulwurf in der WÃ<83>Â
<83>Ã<82>Â<83>Ã<83>Â<82>Ã<82>ÂŒste.avi"/>
</playlist>

After playing about 20 files, the file has grown to 1.1Mb in size of which most is taken up by the enormously long last <item> element.  Now it is noticeable that kmplayer takes a few seconds to start up or close.  After playing a few more files, it is unusable.


Reproducible: Always

Steps to Reproduce:
Start with an empty recent.xml file, play a media file that has an accented character in its name.  Now play some more files, and observe the size and contents of the recent.xml file after each run.


Actual Results:  
The file grows in size every time, and kmplayer performance is affected.


Expected Results:  
The application should behave.


The output above is from less (which shows high-half characters as <hex>).
