Using Debian Sid version of Midori as of Saturday, April 28, 2012, and the most current Seamonkey Nightly Build, I exported my Seamonkey bookmarks, which are fairly sizable, with 109442 listed as its long listing size (they include a lot of tab images and many bookmarks).
When I tried to import the bookmarks.html that I exported from Seamonkey Nightly, I got no response; appeared to hang. First time, I had to kill the browser. Second time I tried, I was able to close the bookmark import, but I still do not see any bookmarks at all.
I could not determine if this duplicates other bookmark issues, but it does seem to be a recurring theme: bookmark importing, exporting, and editing needs a lot of work.
I have attached the bookmarks for your use in testing. Hopefully this will be helpful. For me, improving bookmarks and retention of login information (when explicitly requested) are the two things I would find most helpful; with these features working well, I could envision using Midori a LOT more often!
Thanks!

i could not reproduce this. it takes a while (about 1 min), but it works. (tested with both 0.4.3, which seems to be what sid ships, and 0.4.5a).
there is no visual feedback during the process though, so it does indeed appear to hang (1 minute without feedback feels like an eternity). i could only tell it was doing its work by the noise of the hard drive seeking.
so, maybe you only need to wait a little longer.
btw, to check that it worked it's better to look in the sidepanel; the bookmarks menu in the menubar does not always correctly update.
oh, and you are aware of the privacy implication of posting your bookmarks in a public place, right?
