Running Beta 2 packages from Kubuntu and everytime I browse my music share located on my Windows machine I receive a crash message that generates the following:

Don't know how useful that is or not.  Before updating to 4.3 beta 2 I was able to browse this share without any problems.  Also when I receive this crash message my wireless connection drops and I cannot reconnect until I restart my laptop.
Please let me know how I can further help out.
