Description Reartes Guillermo 2012-10-12 14:35:08 UTC

Description of problem:

If one makes the mistake to switch from English to English, anaconda gets stuck.
Anaconda is not frozen, just stuck, alt+tab works (sadly it does nothing to get out of the situation), one can switch to another vt. Sadly, a reboot is needed.

Version-Release number of selected component (if applicable):
F18b tc3

How reproducible:
always

Steps to Reproduce:
1. enter keyboard, select (click) English
2. press '-' 'minus' button
3. select English from the list again.
4. When you press ADD, anaconda gets stuck.
  
Actual results:
stuck anaconda, reboot and try again. Alternatively do not make this
mistake :-)

Expected results:
an error dialog, a warning? or no error at all. The action itself
does not make sense, but anaconda should not get stuck.


Additional info:
I tried to add two English keyboards using the '+' 'pluss' button and there
was not problem whatsoever. Anaconda did the right thing, the problem is in the
minus button.

Yeah, I see it too.  Looks like we're hitting a traceback, and then the traceback dialog never appears probably due to threading problems that we've got patches in the works for.

In this case everything runs in one thread. The hang is probably caused by removing all layouts from X runtime configuration which may lead to killing X, hang or SIGSEGV (don't know the key determining the result).

Should be an easy fix.

Oh man, I couldn't have been more wrong. It's yet another way to deadlock!

Comment 4 Vratislav Podzimek 2012-10-15 07:42:18 UTC

Patches for both the deadlock (hang) and the traceback sent to anaconda-patches list.

Comment 11 Reartes Guillermo 2012-11-04 19:40:05 UTC

I tried with F18b TC7 and it seems to be effectively fixed.

Comment 12 Adam Williamson 2012-11-23 04:51:39 UTC

This bug looks to have been fixed for many anaconda builds now but missed being closed. If you find you are still experiencing it with Fedora 18 Beta (RC1) or later, please re-open the bug.

(confirmed fixed in Beta RC1)
