can you check if it worked in 3.5.0 beta 2?
https://github.com/joomla/joomla-cms/releases/download/3.5.0-beta2/Joomla_3.5.0-beta2-Beta-Full_Package.zip

@andrepereiradasilva it works with 3.5.0 beta 2. Only issue in 3.5 beta 3

just guessing maybe because of a change that was corrected today (see fc43245)

Can you check if your issue remains in latest staging

I don't think so - that issue was specifically dealing with hashtags that aren't present in the SQL file dump provided. I need some more information please @gunjanpatel - I don't really have enough here to work with

I don't think it should happen in HTML because i have had experience of such errors in XML,not with HTML tags.

@wilsonge I am going to attach installer in which I am having issue. May be it will help to reproduce it.
HelloWorldj3.5.beta3

I can confirm that it works in Joomla 3.5.0-beta2:

While fails in Joomla 3.5.0-beta3:

I could install OK HelloWorldj3.5.beta3 on staging (localhost)

I have been able to isolate the problem. The issue happens when using a # symbol in the sql. This fails:

data.sql:

INSERT IGNORE INTO `#__helloworld_mail` (`mail_id`, `mail_name`, `mail_subject`, `mail_section`, `mail_order_status`, `mail_body`, `published`, `mail_bcc`) VALUES
    (24, 'Order Status Change Pending', 'Order Status Change Pending', 'order_status', 'P', '#', 1, ''),
    (25, 'Order Status Change Confirmed', 'Order Status Change Confirmed', 'order_status', 'C', '#', 1, '');

But if you remove the # at ...'order_status', 'P', '#', 1, ''),... and at ...er_status', 'C', '#', 1, '');

It works

I'm attaching the example component refactored:

com_helloworld.zip

I confirm @infograf768 comment the problem does not happen in staging:

It appears only testing against https://github.com/joomla/joomla-cms/releases/tag/3.5.0-beta3

Then this can be closed then as it has already been fixed
