This is because we do a synchronous read() at the bottom of XDGDBusProxy::launch, and it never completes if spawning bwrap failed. 1960823 1 mcatanzaro 2023-06-09 13:50:53 -0700 Current behavior is we print the following and then hang forever: bwrap: execvp /usr/bin/foo: No such file or directory Proposed behavior is to print then crash (because this is not recoverable): bwrap: execvp /usr/bin/foo: No such file or directory ** (epiphany:203869): ERROR **: 15:49:53.627: Failed to fully launch dbus-proxy: Child process exited with code 1 Trace/breakpoint trap (core dumped) 1960833 2 mcatanzaro 2023-06-09 14:12:40 -0700 Pull request: https://github.com/WebKit/WebKit/pull/14825 1972038 3 ews-feeder 2023-08-18 06:23:32 -0700 Committed 267038@main (971943d9b665): <https://commits.webkit.org/267038@main> Reviewed commits have been landed.
