Public bug reported:
Clean installation of Clementine 1.0.1 uses all the available memory when
attempting to connect/open and scan Windows Phone 7 (MTP) device for the first
time.
"Updating 0%" and "Loading MTP device" appear after confirming first time scan
dialog. Then it starts to allocate inadequate amounts of memory.
Rhythmbox and Nautilus load the library with no issues at all.
My WP7 device: Samsung Omnia 7
Steps to reproduce:
1) Buy a WP7 or Zune device
2) Connect the device to the PC and start Clementine
3) Navigate to "Devices" in the left column
4) Double-click the device (it will be something like this: 045e 04ec)
5) Confirm first-time scan
6) Watch your computer slowly dying and swapping and begging for memory
