Hello,
I am facing some segfaults so I've decided to install GDB and the debug
packages of some Qt5 libs on my phone (Hope that won't cause issues with future
Sailfish updates?).
But this does not help me, since they apparently aren't coming from my code.
For the first, I have a back button on a Map. If I start a flick and I press
the back button while the Map is still flicking, it crashes. But it also
crashes sometimes when the flick has finished so I can't simply test that flick
is finished before doing the pagestack.pop():
Program received signal SIGSEGV, Segmentation fault.

For the second, I have a SilicaListView with images in the sections. If I click
on an Item and come back quickly on this page, once in a while I get:
Program received signal SIGSEGV, Segmentation fault.

Thank you for any advice you can give me. (I can provide the complete backtrace)
