Transmission Crashes With no Error

[slmpika]

Transmission will randomly crash within minutes whether something is downloading or not. Since there is no error, I cannot figure out what could be causing it to crash. Is there a location where a log file or crash report is generated? Are there any known compatibility issues that I should be aware of?

Relevant:
Transmission 2.51
Lubuntu 12.04

I see, I didn't know about syslog. I found the error, but I don't know how to solve it. I've pasted the lines from the log file below, perhaps someone has a solution:

I checked the libevent website and found that there is a newer version than the one listed in Synaptic package manager. (Synaptic has 2.0.16, website has 2.0.19). I had to completely remove libevent and reinstall using the download from the libevent website. I then built the latest nightly build of Transmission and its been open for over an hour now with no problems.

However, this problem is one that will probably affect many Ubuntu users, as you can see that precise (12.04) uses 2.0.16 by default: http://packages.ubuntu.com/search?keywords=libevent-dev . This is not a problem at all with Transmission, but since it is the default torrent application in ubuntu, lubuntu, and probably others, this issue may come up again. I will file a bug in Launchpad.

Can someone please provide step by step instructions on how to get Transmission compiled with the right libevents. I really like transmission but it just isn't working for me at the moment.

I currently have Ubuntu 12.04 and Transmission installed. How do I go about
a) Updating Libevents
b) Updating transmission to use the updated libevents.

I am happy to follow instructions but have not compiled anything on linux before.

Your help would be appreciated.

Thanks

BorderBoetie:

You don't have to compile libevent, you just have to install it from a different repository (quantal, as shown by the link posted by slmpika).

Transmission-GTK doesn't need to be modified, just restarted, it will pick the latest installed dynamic libraries.

Great thanks. Manually installed the updated libevents and from quantal and checking if Transmission stays running.
