Bug 225348 – [GTK] Segfault in ../Source/WebKit/UIProcess/API/glib/IconDatabase.cpp

• Component: WebKitGTK
• Status: RESOLVED DUPLICATE

[Michael Gratton]

WebKitGTK 2.32.0 (libwebkit2gtk-4.0-37:amd64 2.32.0-1ubuntu3)
Epiphany 40 (epiphany-browser 40.0-2)

Initial crash occurred at some point during normal browsing. On start Ephy now crashes with the following stack, 100% of the time:

Thread 1 "epiphany" received signal SIGSEGV, Segmentation fault.

FWIW, moving ~/.cache/epiphany/icondatabase out the way stops Epphy crashing at least.

This is probably related to bug #225279 — maybe even the same.

[Michael Gratton]

FWIW, the page causing this seems to be: https://medium.com/@andreasreiser94/why-hateoas-is-useless-and-what-that-means-for-rest-a65194471bc8

As soon as I loaded that again got a segfault.

With the patch for bug #225279 applied I cannot hit the segfault
loading that URL—thanks for providing a link to reproduce, I am
confident now that this has the same root cause =)
