QT5.4: Sdcard not shown in ciborium app

[Dave Morley]

STEPS:
1. Install latest vivid on krillin
2. citrain silo 5 onto the device
3. Open the External drives app

EXPECTED:
I expect to see the sdcard and some options to remove and format it

ACTUAL:
The app just has a blank page.

More information about using Qt 5.4 (targeted before Feature Freeze Feb 19) at https://wiki.ubuntu.com/Touch/QtTesting

I don't think it'sa blank page, i think it is actually crashing, if you let it open for a while, you'll see it disappear and if you start it from the command line it crashes.

I tried to debug why/where it's crashing but it being go-based i can't get gdb or valgrind to tell me anything interesting.

Installing dbg for libc we get

And commenting all the code in internalLogHandler makes the crash go away, need to find out how to fix it next
