Lucid netbook-launcher segfaults when started

[Ronald McCollam]

Binary package hint: netbook-launcher

When booting in live mode from a USB stick with the 20091209 build of UNR, the launcher is not displayed. Opening a terminal and running netbook-launcher produces a segmentation fault:

I can confirm this to occur on an HP Mini 1000.

[Carl Heymann (ch-heymann)]

Also happening to me on an MSI Wind U100. I'm seeing lines like this repeated on /var/log/messages.

netbook-launcher doesn't stop, and keeps on using CPU. I can keep on using the computer though, but the netbook remix interface doesn't start up.

[Matt Drake (mattduckman)]

here's backtrace of the crash

[Martin Pitt (pitti)]

Neil, until Didier starts, would you have some time to look into this? Thanks!

[George Kontis (giormatsis)]

I get this error with seamonkey

(seamonkey-bin:4402): GLib-WARNING **: g_set_prgname() called multiple times

[Omer Akram (om26er)]

plz resolve this one.

[Antti Kaihola (akaihola)]

Identical symptoms on a Dell Mini 9 with http://cdimage.ubuntu.com/ubuntu-netbook-remix/daily-live/20091223/lucid-netbook-i386.iso

Same messages in .xsession-errors as shown in the bug description, and the netbook launcher never appears.

[bob gray (sooner-inbox)]

Same problem.

[Omer Akram (om26er)]

can this be related with mesa?

[Antti Kaihola (akaihola)]

On my Dell Mini 9, the Live CD behaves as described above.

However, when installed onto the internal SSD, Ubuntu Netbook automatically logs in to the standard GNOME desktop by default instead of the netbook interface. If I log out and select the Netbook interface, I get the symptoms described in the description of this bug.

I did the install from a USB stick created with unetbootin with all default choices except the Finnish locale and enabling popularity contest.

I tested both the live and installed desktop using http://cdimage.ubuntu.com/ubuntu-netbook-remix/daily-live/20100102/lucid-netbook-i386.iso

[Omer Akram (om26er)]

6days to alpha2 and still no news?

[Didier Roche-Tolomelli (didrocks)]

Thanks all for your interest in Ubuntu Netbook Edition. This bug will be fixed in alpha2.
(For the record, I'll be full time on it beginning next week)

[Omer Akram (om26er)]

yes, its fixed thanx.

[mexlinux (mcanedo)]

This is happening to me in karmic

[Owais Lone (loneowais)]

Any backport available for Karmic?

[RachaelB (8-launchpad-rlb-me)]

netbook-launcher *was* working fine... now it isnt in Karmic :(

extract from syslog:

[Ryan Waldroop (ryan.waldroop)]

This bug is back. Running 2010-02-09 lucid-netbook-i386.iso.

[Didier Roche-Tolomelli (didrocks)]

Ryan: there has been some transitional work on yesterday's image. Can you confirm it's no more the case on 2010-02-10?

[James Miller (bladeon)]

I am encountering this bug in the latest version of netbook remix. On initial install it worked fine, when I installed fglrx, netbook remix started to segfault. I can otherwise use the system fine, just netbook-launcher is failing.
