Choosing "Watch Videos" Crashes Mythfrontend

[Dave Sp <davespmyth@…>]

Around 75% of the time, when I choose "Watch Videos", mythfrontend crashes. Retrying works the rest of the time.

Source was pulled from git branch fixes/0.24 as of today. "make distclean" and "configure" were done prior to compiling.

Backtrace shows:

Program received signal SIGSEGV, Segmentation fault.

What other information can I grab to help figure this out?

This ticket can be closed.

My Intel hardware may be a little out of whack, although memtest86+ RAM tests are okay and I run the hardware with clock-skewing disabled. Other Intel hardware running the same binary (although on a different Intel motherboard) works without faults. I'll open a new ticket if I get something reproducible on multiple platforms.

Initialize the MythUIImage filename correctly

Fixes #9634. Fixes #9708. Refs #9547.

If the filename does not start with "/", "​http://", "​https://" or "​ftp://", then the actual filename loaded is uninitialized. It can be any random crap on the stack. I'm honestly surprised this worked at all :)

This may fix things for #9547 as well, and should be tested with that scenario too.

Could be worth trying the updated code, but the above commit has been reverted.

Reclosing at user request. Not sure why I re-opened this.
