9 years ago While I can confirm this problem, it does not occur if it is run via gdb.

Quite amazingly, this turned out to be not an actual freeze but a performance issue (the output does show up – if you have about 30 minutes patience, that is...). Final Term had huge performance deficits when rendering really long lines such as the ones produced by ps e, which are now gone.
Runs fine under gdb, but gets this attaching gdb on the fly:

It looks like we could have a good suspect in explode (TerminalOutput.vala, line 925), but I have no idea on how to fix it. ps termlet doesn’t look like the culprit here, as a (lightly) modify ps termlet runs fine under gnome-terminal. Hope this helps to track that one.
