Crash on email.seznam.cz #15

Closed pepalogik closed 9 years ago

pepalogik commented 9 years ago

Fifth sometimes crashes in the web-mail interface of seznam.cz. This interface seems to be ajax-based. I cannot state a specific condition when it crashes, but it seems that it happens preferably when performing some action after a while of inactivity.

This will be hardly reproducible for you: You would have to create an account there, have some e-mails there and work with them, while the interface is in Czech. However, here is some gdb output:

Is that helpful? I have not yet terminated gdb, so I can execute more gdb commands if you wish and if you reply quickly.

I'm afraid the backtrace doesn't tell much, and it can't do so without you installing the debug versions of openssl and curl, and restarting gdb (ie. you can safely turn your computer off, the current gdb session isn't needed). It's deep in those libs, and so likely a bug in either openssl or curl, instead of fifth/webkitfltk.

clbr commented 9 years ago

Yep, curl bug. Closing.
