You forgot to include what version of Sublime Text you are using and what architecture (32 or 64 bit).

For what it's worth, I just opened a folder in ST 3168 on Ubuntu 18.04 (which is only available for 64 bit architectures) and it didn't crash. I'm guessing the OP's crash was fixed in 3167, which has a changelog entry:

Fixed a crash when adding folders to the sidebar with a complex combination of hardlinks and symlinks

I think I'm having the same issue, although Sublime doesn't crash but just freezes and just waits there to be killed. It happens when invoking open/save file dialog in any way, eg. by hitting Open File, Open Folder or Save As options from menu.

Sublime Text version 3.0 build 3143
Fresh install of Ubuntu 18.04 64bit

Just tried 3168 and as @keith-hall stated, it doesn't happen anymore! :D/

Same issue with build 3143 and snap package.

Similar problem here. When opening it's all ok, but when "save as" it freezes and waits for me to kill the app.
Sublime V 3.0 Build 3170 installed via Snap
Ubuntu 18.04 fresh install

If you have a license, you may want to try build 3173, some crash bugs were fixed, probably including this one

Not able to buy a license (yet). Removed snap, installed from apt-get adding site's repository, works as a charm now. Thanks anyway

Hmm, I would try not using unofficial sources. It is going to be hard for us to try and support them.

Sorry, I wasn't clear; I added the file "sublimetext.list" containing the text "download.sublime-text.com/ apt/dev" to mi "/etc/apt/sources.list.d" folder, thus downloading and installing directly via sublime-text's site repo and not from the snap. Now it works fine

Sorry @SimonLKP, I did understand you. Based on your report about the snap issue, I made my comment mostly for @Dremon and @dixiematt8.

It seems this was resolved, closing.
