[Interest] Unable to make deb file of Qt 5.5 app in Ubuntu 14.04

[Igor Mironchik]

Hi,

I guess that this is the same issue that I had already.

This happens because Ubuntu uses QT_PLUGIN_PATH set in the system.

Try to set this environment variable somewhere in the shell and 
run/build you application.

Something like this:

export QT_PLUGIN_PATH=

for example in bashrc and run you app from the shell...
