The first time, spamming Ctrl-G somewhere around 30 times gets it to continue. Triggering the freeze again renders spacemacs unresponsive (entirely) until the process is killed (either by force quit or the `kill` command). During both 'phases', emacs uses upwards of 99% CPU.\r\n\r\n#### Reproduction guide :beetle:\r\n- Start Emacs\r\n- Split window\r\n- Open files in each window (I just opened .spacemacs while recreating for screenshots)\r\n- Either use normally with standard M-x use, or press M-x bind (SPC-SPC or SPC-:) and cancel repeatedly until freeze\r\n- Ctrl-g spam to \"unfreeze\" and bring up the M-x helm minibuffer as intended\r\n- Close minibuffer, repeat M-x opening step\r\n\r\nNote that I don't just sit there spamming SPC-SPC for fun. The freeze inevitably happens, it's just convenient for demonstration to be able to quickly reproduce it.\r\n\r\n*Observed behaviour:* :eyes:\r\nEmacs freezes with a solid, relatively thin black, vertical bar on the screen and does not visibly respond. C-g spam can 'recover' it once; repeating the freeze procedure causes emacs to be completely unresponsive and consume 99%+ CPU (according to activity monitor).\r\n\r\n*Expected behaviour:* :broken_heart:\r\nOpen M-x menu without freeze or black bar.\r\n\r\n#### System Info :computer:\r\n- OS: darwin\r\n- Emacs: 25.0.94.1\r\n- Spacemacs: 0.105.20\r\n- Spacemacs branch: develop (rev. 0a973c0)\r\n- Graphic display: t\r\n- Distribution: spacemacs\r\n- Editing style: vim\r\n- Completion: helm\r\n- Layers:\r\n```elisp\r\n(auto-completion\r\n (auto-completion :variables auto-completion-enable-help-tooltip t auto-completion-return-key-behavior 'complete auto-completion-tab-key-behavior 'cycle auto-completion-complete-with-key-sequence nil auto-completion-complete-with-key-sequence-delay 0.1 auto-completion-private-snippets-directory nil)\r\n csv javascript html helm emacs-lisp git org osx python ranger renpy smtheme)\r\n```\r\n\r\nNote: smtheme layer is just the jellybeans theme.\r\n\r\n#### Backtrace :paw_prints:\r\n```\r\n<<BACKTRACE IF RELEVANT>>\r\n\r\n```\r\nAttempts to resolve:\r\n- Delete elpa and redownload packages\r\n- Try master instead of developer\r\n- Reinstall emacs\r\n\r\nThe bar can be seen here on the right side of the left window. It goes from the top of the frame to the bottom, covering all buffer text and the \"ni\" in \"unix\". Note the SPC-SPC in the lower left.\r\n![ss_2016-06-06_19 10 57](https://cloud.githubusercontent.com/assets/8557981/15841094/76f77e9c-2c1c-11e6-9595-c4d81c82aa80.png)\r\n\r\nHere is a screenshot of activity monitor to show emacs' CPU usage.
