Can't index Greek modules in Bibletime 2.8.1 in 12.04

I've used Bibletime for a while, but in 12.04 I seem to be having a lot of trouble with it that I don't have in my 11.10 machine.

Distributor ID: Ubuntu
Description: Ubuntu 12.04.1 LTS
Release: 12.04
Codename: precise

Bibletime: 2.8.1-2build1
libsword9: 1.6.2+dfsg-3

The main problem is that Bibltime won't index Greek modules for search, but it will index e.g. English or German modules.
Steps:
  1. Install e.g. SBLGNT module via Bookshelf Manager;
  2. Select the Search Indexes option on the left in Bookshelf Manager;
  3. Select a Greek module (I've tried both the SBLGNT and TR modules) for indexing, and click Create;
  4. The Greek module now shows up in the Indexed Works list, but the index size is 0 KiB, and searching returns no results.

I am able to index Greek modules in Xiphos, so I tentatively infer that the problem is with Bibletime and not libsword.

A different problem is that I can't use the Bookshelf Manager to remove a module I've installed.
Steps:
  1. Open Bookshelf Manager;
  2. Select a Bible module (I've tried ESV, SBLGNT, TR) for removal and click Remove;
  3. Confirm removal in the dialog box that pops up;
  4. Nothing happens: the module is still installed.

I've noticed other problems as well, and I suspect others have too. I'd like to install a different version, but I can't back down to the 11.10 build because it depends on libsword8, which in turn depends on libicu44 rather than libicu48, and those libraries seem to be deeply implicated in the dependency graph.

Any suggestions? I saw the answer at
  https://answers.launchpad.net/ubuntu/+source/bibletime/+question/180536
but it appears that this solution won't work for me, since the current bibletime build at Crosswire (2.9.1-1~ppa2~precise) depends on libsword8, for which there is no candidate.

Perhaps the answer is to build bibletime from source, with the libsword-dev package for my current libsword9.
