user/gwenview: fix stack size overflow
When opening a .CR2 Canon RAW image, attempting to load the embedded
preview for the thumbnail bar would result in a segmentation fault on
at least x86_64, with the backtrace:
Thread 4 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

This is because the thumbnail was being loaded onto the thread's stack.
Bumping the per-thread stack size to 1 MiB fixes this for all .CR2 files
I have access to.
