Comment 1 Jaime Torres 2013-07-02 19:55:35 UTC
This crash happens to every KDE program that tries to walk into my home directory (almost all).
Just because I had a file in that directory with a very strange name, just to test things like this. To be able to move that file from a KDE application to another place.
The file name is:
\|\|\|\|$'\026'$'\026'$'\026'$'\026'$'\207'$'\207'$'\207'$'\207'$'\377'$'\377'$'\377'$'\377'\(\(\(\($'\255'$'\255'$'\255'$'\255'$'\324'$'\324'$'\324'$'\324'\`\`\`\`$'\373'$'\373'$'\373'$'\373'$'\333'$'\333'$'\333'$'\333'NNNN$'\v'$'\v'$'\v'$'\v'FFFF$'\335'$'\335'$'\335'$'\335'JJJJ$'\275'$'\275'$'\275'$'\275'$'\364'$'\364'$'\364'$'\364'$'\333'$'\333'$'\333'$'\333'MMMM
Once I've moved that file to a rarely used directory (not in /home), the crashes are gone, except when trying to navigate to that directory: dolphin and the open dialog freeze.

Probably related to commit f4269ef3498581964e8a1a13cd0d6d7f19c88762 ?

Yep, kio_file crashes when visiting a directory with such a file with Dolphin.
Róbert, could you have a look?
