Doing "wget http://feeds.weblogssl.com/motorpasion"
you get the file motorpasion. You can add the suffix .xml if you want.
opening the file with kate (or kwrite) takes more than 5 minutes.

If you divide the file in lines with
xmllint --format motorpasion.xml >motorpasion1.xml

and open the new file, it takes less than 1 minute to open.


Reproducible: Always



Expected Results:  
If the lines are too wide, to apply a forced line wrap (for example).



In any case, this could be used to improve the performance of the code causing the slowdown (if you have enougth patiente and time).
