Bug 497108

SUMMARY
Encrypted .odt files within an opened folder cause continuous errors and icons fail to load if multiple encrypted documents are in one folder

STEPS TO REPRODUCE
1. create a writer file in libreoffice with an encryption password, save with .odt file extension
2. navigate to the folder with the file

OBSERVED RESULT
a continuous error will pop when dolphin attempts to access the file's icon or upon loading, something? not actually attempting to open the file. But when attempting to open or open properties, only this error will show up.
"This document contains an unknown encryption method. Some parts may be unreadable."
Some files also throw:
"This document contains an unknown checksum. When you give a password it might not be verified."

File is still accessible outside of dolphin when opened through libreoffice

EXPECTED RESULT
no errors, and properties page opens properly , as well as opening file opens properly
