how Helix deal with the scenarion that a usb disk is pluged out during playback?

When Helix player is playing content on USB disk, then user unplug the
USB disk, helix engine will crash in such scenario.

I test it for helix-player and player_gtk_test on Linux, helix engine
will crash in such scenario. 

On Windows system, Realplayer works well in such scenario, the
presentation stopped, but you could open another stream.

 

When I looked into some source code at
filesystem/local/full/smplfsys.cpp, 

I found there seems to be some function to deal with such scenario:
CheckForCorruptFile().

However, when I try to debug it, I found the function isn't invoked in
the scenario above.

 

And I found after the last call to FinishDoRead(), the engine crash.

But in this last call, for the condition sentence to
CheckForCorruptFile():

if (!pBuffer || actual < m_ulPendingReadCount)

 

the pBuffer is valid and actual = 2048, and m_ulPendingReadCount = 2048.

 

I think the scenario should be a common error handle for source plugin, 

Did anybody meet such issue before? Or maybe someone fix it in other
branch?
