Bug #61851	transactions fault across connections

Status:	Duplicate	Impact on me:	None
Category:	MySQL Workbench: SQL Editor	Severity:	S3 (Non-critical)
Version:	5.2.34 revision 7780	OS:	Windows (XP professional)
Assigned to:		CPU Architecture:	Any

Description:
When making two connections to the same database initiate a transaction in one connection. attempting to start a transaction in the second connection after a transaction has taken place in the first connection (i.e. even if the transaction in the first connection has committed) causes the "Report a bug" to appear stating:

Mysql Workbench unexpected error.
External component has thrown an exception

How to repeat:
Start Mysql Workbench
open a connection to a database
open a second connection to the same database
in the first connection - START TRANSACTION
in the first connection - do something e.g. select contents of a table
in the first connection - COMMIT
in the second connection - START TRANSACTION    <- this will error

Suggested fix:
each connection made in workbench should act as a separate connection e.g. the same as if one was made using command-line mysql and the other was made using workbench - each has no knowledge of the other.

Thank you for the bug report. Verified with version 5.2.34.2 on Windows XP.

Stack trace is:
