I installed today: and enabled FileManager pluging. Works fine. I guess that the CodeBlocks ebuild should be modified that it installs app-admin/gamin and dev-libs/libgamin. Will test and if appropriate file a bug report.
I already planing to modify ebuild among other changes (as co-maintainer). You could see the status in
pull request. There are several changes and it could be take some time to check them by wxwidgets team.
The dependency of only dev-libs/libgamin was inherited from 16.01 ebuild. I was asked about dependency early of virtual/fam (app-admin/gamin or app-admin/fam) but I never encounter this crash until recent time during testing of ebuilds on the machine there I have no installed gam-server package. But on the second system it's instaled as dependency of samba and kcoreaddons (by USE="fam").
The "FileManager" plugin could be linking only with app-admin/gamin (but not with app-admin/fam or gfilemonitor from dev-libs/glib) that is meta package for dev-libs/libgamin and app-admin/gam-server. There is appropriate
ticket in codeblocks bugzilla to update FileManager dependency in favor of more fresh library.
Also I'm planing to update codeblocks-9999.ebuild by syncing it with updated 17-12.r1 ebuild as current seems to be broken to build contrib-plugins (I have no idea why but updated works for me). It allows to install codeblocks from snv.

could you confirm that you have installed app-admin/gam-server package besides dev-libs/libgamin
