I have upgraded to TeXStudio 2.6.6 via the package manager in Ubuntu 12.04 LTS since the one in the repository was way too old. However, when I launch the application and try to open a file or check Latex installation an error box appears as I added here. Furthermore, when I click OK the system crashes and I cannot open the terminal or close TeXStudio leaving me with no choice but to restart the computer by holding the power button. I have tried reinstalling and uninstalling multiple times with no solution and would greatly appreciate any help and suggestions provided.
EDIT: The problem is solved I found a dictionary with featuring two files one with .aff extension and the other with .dic extension. However, I am still puzzled about how a missing dictionary in a program can crash the whole system. Thanks in advance
