Are you positive your test machine is Ubuntu Linux 14.04 LTS? I was concerned that my very minor font customizations to the system might have been a problem like you suggested so I reverted those changes back to the system default and have the same issues.
In addition I installed a brand new clean copy of Ubuntu 14.04 onto a VMware image, installed Oracle JRE 8 update 25, downloaded and installed The Brain. Created a test brain and have the same issues (no drag and drop functionality, foreign characters when pasting rich text). Nothing
else was changed with the install.
I will submit a formal support ticket but I find it really surprising that you are not encountering any of these issues yourself.
Are there any other Ubuntu users out there that can comment?
I tried a few different flavors of Java and got some results with the drag & drop. The pasting of text is broken still in all versions I tried.
Oracle Java 8 update 25: drag n' drop does NOT work
Oracle Java 7 update 71: drag n' drop DOES work. Sort of. An exception is thrown when you drop the file and it also then hangs when you try to exit TheBrain (below).
OpenJDK 1.7.0_65: drag and drop DOES work with same issues as Oracle version.
Exception from drop:

Exception after Ctrl-C because TheBrain hangs on quit:
