Replying to myself, here're more infos I managed to get with gdb by
killing E while it is eating cpu. The problem seems located in
ecore_desktop_get_command.

And just in case, here's the content of the .desktop :
[Desktop Entry]
Type=Application
Encoding=UTF-8
Name=Electric Eyes
Comment=Electric Eyes image viewer
Icon=ee.png
Name[C]=Electric Eyes
Comment[C]=Electric Eyes image viewer
Exec=/usr/bin/ee
Terminal=false
MimeType=image/gif;image/jpeg;image/png;image/tiff;image/x-xbm;image/x-xpm;
Categories=X-MandrivaLinux-Multimedia-Graphics;
So, it seems the list is growing forever (37 M entries so far), due to
ecore_list_append being called repeatedly, but I'm not familiar enough
with the .desktop part in ecore to see what causes this.
Hope this helps.
Bye
Nicolas
