+Failed attempt to make poppler quiet

+Do not forget to add poppler to pkgconfig-depends.
+
+Neither setting error callback nor setting global param makes
+poppler quiet. It seems that the errQuiet flag is set
+and the changes are visible inside poppler.cc, however
+they seem not to be visible by poppler library. I probably
+do something wrong.
