Same problem here with Chakra Linux 64bit
http://paste.chakra-project.org/6476/

[Ernst Martin Witte]

Could reproduce the issue with the stream mms://bcr.media.hinet.net/RA000072 and libav* 2.1.4.

Reason was an erroneous error handling and missing support for floating-point sample formats in kradio.

The segfault is fixed now in 6aae9c33ed53bc2470cdc4b5c145eb1bb72f452a. However, more patches are required to support floating point sample formats.

Finally fixed in 7da1a55476181dd4f25bd7d46fe142a505c1aa1e. Will be part of KRadio4 4.0.8
