PSR is disabled because it causes issues such as this among others which we try
to fix here, so it can be enabled again somewhere in future. It seems we
finally found source of this issue: DRRS is enabled with PSR which shouldn't be
allowed. It puzzles me why after year long discussions, two bug reports, asking
for providing more and more logs you finally come to conclusion that it isn't
supported.

Is something wrong with this? Should I test it?
