Application crashing when corrupt image is decoded, can't try-catch

[nlw0]

I'm writing a Gtk app where png images get decoded by ImageMagick.jl. Sometimes I hit a corrupt file, and this ends up triggering these lines

ImageMagick.jl/src/libmagickwand.jl

Line 187 in 39cf88a

error(msg)

ImageMagick.jl/src/libmagickwand.jl

Line 286 in 39cf88a

status == 0 && error(wand)

Right now this ends up making my application crash. I would like to try-catch here and recover, if possible. Are there any changes that would be necessary in the library, or am I doing something wrong?

The title here says, "can't try/catch, but I don't understand why that doesn't work. Are you calling this from a Gtk callback? Do you need a @guarded? Does it work if you try to load one of the busted files from the REPL rather than your Gtk application?

It's hard for me to reproduce this now, sorry I guess I was fishing for a bug. try-catching load_ works fine in the REPL, I guess if there was any issues it's in my code.
