transmission-gtk crashed with SIGSEGV in event_base_loop()

[Alexey Sveshnikov]

Binary package hint: transmission

Actually, every program at my laptop is crashed time to time. Even bugreporting tool :)
It is crashed in Unity, KDE and XFCE.

I'm sending bugreport for transmission because the size of reports is reasonly big (53M), so I hope it can help to find the real problem.

Hi Alexey,

Thanks for reporting this crash and helping to make Ubuntu and Transmission better.

Looking over the backtrace, I have two questions to start with: (1) Is this a repeatable crash? (2) did this happen during shutdown?

[Alexey Sveshnikov (mahoro)]

Hi!

1. Yes, it is repeatable, but only when wi-fi is active. I found out that when I use wi-fi the system at all is very unstable. Transmission, browsers, bug reporting tools - all that stuff may freeze at any moment.

So I think this is not a transmission problem, but a wi-fi drivers.

2. No.

P.S I have Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller, which handled by brcm80211 driver (I guess). I'll post a bug about it shortly.

I've had this crash when I select the option to delete a torrent and its files (with 2 torrents selected).
