Bug 443791

Hm, this does not seem right.

I am wondering what is the sunbird doing (probably it is loading remote
calendars or something like that.) Is this a clean installation and first run,
or was it already configured?

To see what happens, please try either the following:

1.) Install "strace" package, and run sunbird from Terminal as follows:

$ strace -f -o sunbird-strace.log sunbird

When the sunbird enters the state you described above, please terminate it and
attache the sunbird-strace.log here. (Before doing so, please open it in a text
ediror and ensure it contains no private data, such as passwords. In case it
does, please delete it. Also, you might want to attach it as private attachment).

2.) Do "debuginfo-install sunbird", run sunbird, and once it freezes please
attach the debugger as follows:

$ gdb -p `pidof sunbird`

Once you get GDB prompt, obtain the stack traces as follows:

(gdb) set pagination off
(gdb) set logging file sunbird-gdb.log
(gdb) set logging on
(gdb) thread apply all bt
(gdb) quit

Please attach the sunbird-gdb.log file here.

Thanks!

Strace was the easiest (already installed)

It is just a fresh install and a first run.

2330  writev(23, [{"*** glibc detected *** ", 23},
{"/usr/lib64/sunbird-0.7/sunbird-b"..., 34}, {": ", 2}, {"free(): invalid
pointer", 23}, {": 0x", 4}, {"00000000018470b0", 16}, {" ***\n", 5}], 7) = 107

Hm, it seems that sunbird crashed for some reason (no it did not close yet).

Does this allways happen? Do you allways see the "*** glibc detected ..."
message followed the backtrace when run sunbird in terminal?

Have you tried creating another profile and using it by running "sunbird
-ProfileManager"?

Also, I will try to build sunbird-0.8 for F8 and post you a link to it, so that
you can try if you can reproduce it with later version.

Yes I always see : *** glibc detected ...

I'm not sure how to create another profile. Is sunbird not creating one the first
time it runs? I think this one is created in ~/.mozilla/sunbird. Before
installing sunbird I did not have this directory. So it must be created before
the program hangs.

Lets hope that 0.8 will help.

This is too bad. Do you have a fully-updated clean installation?

Yep, you're right. You can either force sunbird to create a default profile by
moving .mozilla/sunbird away, or can create one by hand with "sunbird
-ProfileManager"

> Lets hope that 0.8 will help.

Seems like the check for the tag being in respective branch is in effect even
for scratch builds, and 0.8 was never in F-8 branch, so the build failed. I can
try creating a branch with 0.8 for F-8 and building that though.

>This is too bad. Do you have a fully-updated clean installation?
as far as I know. I just did a yum (from yumex) yesterday to install the package.
I got no error messages.

I was running it for the first time so it is a fresh/default profile.
Running with -ProfileManager and creating a new profile results in the same hang.

After an upgrade to F9 the problem is gone. So the problem seems to be limited
to F8. (this means from now on I do not have a machine to reproduce the problem)
