According to some old posts, this bug appeared in 0.22 and is still present in 0.23. It worked fine in 0.21. Reference post with stack trace: http://www.gossamer-threads.com/lists/mythtv/users/411232 I have been running for several days with my patch, and it's working well. I am using 0.23-fixes. The bug is that QFSFileEnginePrivate::nativeRead does not correctly exit from its read loop when the end-of-stream is reached. Instead, it gets stuck in a loop with errno==EINTR. GDB backtrace: - 0 0x9029d153 in fgetc () - 1 0x8ea6acee in QFSFileEnginePrivate::nativeRead () - 2 0x8ea2e1e0 in QFile::readData () - 3 0x8ea34440 in QIODevice::read () - 4 0x8cfb397e in copy () Though the actual bug is likely down inside Qt, isolating that with a proper test case and producing a safe/correct fix is too high a barrier, so I hope this workaround will suffice for now. ./mythbackend.intel --version Please attach all output as a file in bug reports.
