Observed result
SUMMARY
Entering relative paths to the document title field corrupts .kra files on save
through a ZIP directory traversal bug.
KDE Ark also flags these archives as "contains ill-formed entries and might be
a malicious archive".
STEPS TO REPRODUCE
1. Create a new document
2. File -> Document Information -> General -> Title
3. Enter "../../../../../test/" as the document title (without quotes)
4. Save as .kra and close the document
5. Reopen the document
OBSERVED RESULT
See attachment.
EXPECTED RESULT
Don't corrupt documents on save whatever the document title is.
