Subject: Fix a bug in receiving data from the server
X-Git-Url: http://git.tdb.fi/?p=xinema.git;a=commitdiff_plain;h=5bb8258cd0c2a5600bc90ac9f7dc06b4746a16f9

Fix a bug in receiving data from the server

QIODevice::readyRead is edge-triggered, not level-triggered.  Thus it
can't be relied on to be triggered again if only part of the available
data is read.
