Package: epiphany-browser
Version: 2.22.3-1
Severity: serious
Hello,
thanks for maintaining epiphany.
I got a recurring, reproducible segfault when changing the text size.
It does not happen in every website, but for those when it happens, it
happens consistently.
How to reproduce it:
$ epiphany-browser http://www.bbc.co.uk/food/recipes/
Hit ^+ or ^- to change the font size, or choose View/Larger text (or
Smaller text) -> Segmentation fault
I installed epiphany-browser-dbg to get a stack trace, here it is:
$ gdb --args epiphany-browser http://www.bbc.co.uk/food/recipes/
