As fas as I can remember, I already add issues when installing Texstudio 
from AUR, and you are right, I compiled it from source with using AUR.
The package is not outdated according to the maintainer, and one user 
with same issue as mine claimed he didn't use packagemanager to install 
texstudio first time, so his old installation was messed up with the new 
one. It seems I have same problem, but I do not know how to solve it.
Most of all the conflicting files are .png, html  or files, except fot 
the binary /usr/bin/studio. So I guess I can force the install, but 
don't know how to do it.
