Description of problem: Folding in vim-latex does not work with vim-7.4.640-4.fc22 but it does work e.g. with vim-7.4.663-3.fc23 locallly compiled for Fedora 22. Version-Release number of selected component (if applicable): vim-7.4.640-4.fc22 Can you please update vim in Fedora 22 to at least vim-7.4.663-3? If you do not have the time, I can do this for you as well.
I'll prepare a new vim package soon (7.4.827 or newer). Please try again with that and reopen this bugzilla if you can still reproduce this issue
vim-7.4.827-1.fc21 has been submitted as an update to Fedora 21. https://bodhi.fedoraproject.org/updates/FEDORA-2015-14209
vim-7.4.827-1.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report.
