I installed guipdftk from the openSUSE Build Service but when I run the software I get the following error message
File not open.
Press OK to ignore and risk data corruption.
Press Cancel to kill the program.
And, when I run it through terminal I got another error message
al7oot@xfce:~> guipdftk
[WARNING] Out of OEM specific VK codes, changing to unassigned
[WARNING] Out of unassigned VK codes, assigning $FF
TApplication.HandleException File not open

Does anyone know how to troubleshoot this bug? Thanks
