Well, it's been two years since I started this thread, and despite the fact that Jeromeg chose to edit my first post in this thread, to add two solutions to it and mark it as "Solved" a long, long time ago, the issue has never been solved for me. In fact, it was such an important problem that, two years ago, I ended up downgrading all of my systems back to Debian Squeeze with Xfce 4.6, mainly to get rid of this problem in Xfce 4.8.
I've waited for the past two years, hoping that this problem would finally be solved by the time Debian Wheezy became Debian Stable. Several days ago, Wheezy became Debian Stable, so I upgraded to it, only to discover that this problem still exists -- and after wasting several hours on Google searches, all I've really learned is that nearly everyone who has written about this serious issue seems to think that simply shifting the 30-second delay from the very first Thunar startup to the very first network access is "a great solution."
Well, it's not a solution for me, or for any other computer users who access network shares.
All of my systems run NFS to access my shared file storage, and they all need to be able to access those shared files immediately - so the "solution" described above that disables AutoMount is not solution for me at all - it simply makes me wait an incredibly long time the first time I try to access files on my NFS share, which is almost always immediately after boot.
And using Thunar 1.6.0 is not an option for me either -- currently Thunar 1.6.x is only available to me in the Debian Experimental repository -- not an option for those of us who are running Debian Stable (Wheezy). And even if someone were to backport Thunar 1.6.x, I still can't find any information to tell me if the 30-second delay problem has actually been SOLVED in Thunar 1.6.0, or if Thunar 1.6.0 simply includes the delay-shifting non-solution described above.
So, to try to "solve" the problem, I've installed PCManFM, which doesn't have the problem at all. It starts instantly every time and lets me access my NFS shares instantly, too - no delays at all, even though it's accessing my network each time. Unfortunately, PCManFM doesn't have Thunar's Custom Actions feature, AFAIK, but I can live with that inconvenience a lot easier than this one.
