Solution:
Execute the following command to create a symlink to the current version of swt:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

SmartGit Hangs When Switching Branches

Problem:
On Windows, SmartGit Hangs when switching braches, with the message:

Process Not Responding
SmartGit is waiting for the following process to finish.
C:\Program Files(x86)\Git\bin\git.exe ls-remote origin
If you thnk the process is hanging, click the Exit Process button, otherwise Wait

Solution:
Install an earlier version of msysgit to eliminate this issue.

This error popped up in version 1.7.10 (Git-1.7.10-preview20120409.exe) of msysgit.   This error was confirmed absent from versions 1.7.9 (Git-1.7.9-preview20120201.exe) and 1.7.8 (Git-1.7.8-preview20111206.exe)  of msysgit.

UPDATE (2012-04-24):

This bug was fixed in SmartGit 3.0.4 (2012-04-21):

Switch (Git): hangs for https repositories with (msys)Git 1.7.9.2 or newer

SmartGit SSL Certificate Problem, error:14090086:SSL

Problem:

You get error:14090086:SSL in SmartGit when trying to clone a remote repository using HTTPS (SSL):

Solution (Windows):

1.  Create a new directory called <project_name>

2. Right-Click on the new directory and select "Git Bash Here"

3.  Enter the following command lines:

git init

git config http.sslVerify false

git remote add origin https://</Bonobo.Git.Server/Git.aspx/pylet

4. Close the Git Bash

5. Open SmartGit and open the existing local repository, and click the Pull button

Warning:

This solution is a security risk if ever used with an external site and is intended for intranet servers with self-signed ssl certificates.  Do not use this solution with public servers and if your repository is ever moved to an external site, you will want to switch http.sslVerify back to true.

You might see examples using a global setting (git config --global http.sslverify "false") .  In the solution presented here, we are intentionally disabling SSL verification on a per repository basis so you can still safely use public repositories.
